<div class="field field--name-body field--type-text-with-summary field--label-hidden field__item" id="id-body"><p>The environmental history of Colorado is a story of the interplay among land, labor, and leisure. By land, I mean the summation of all the things in the environment that Coloradans did not make: the <a href="https://coloradoencyclopedia.org/article/colorado-climate"><strong>climate</strong></a>, topography, sunshine, soil fertility, minerals, plants, animals, germs, <a href="https://coloradoencyclopedia.org/article/water-colorado"><strong>water</strong></a>, and more. Labor is the work—most basically, the energy—that people invest in modifying the land to make it more conducive to human habitation and to produce wealth. As Coloradans have labored successfully, they have produced sufficient bounty to relieve themselves of some labor, giving them time and treasure to spend on things not of immediate necessity. This is leisure. Most obviously, leisure includes recreation, such as skiing or backpacking. But Coloradans have also appreciated science, aesthetics, education, and spiritual renewal—things that, while not of daily material necessity, nevertheless have great value, cultural value. So land comes first. Then humans modify it. Successful modification enables leisure. Sometimes they follow sequentially. Sometimes they interact all at once. Together, land, labor, and leisure can help us trace a timeline of the Colorado environment, from the earliest human occupancy to the present.</p>&#13; &#13; <h2> Timeline</h2>&#13; &#13; <p>Colorado’s modern <a href="/article/colorado-geology"><strong>landscape formed</strong></a>, for the most part, over the last 70 million years or so. For 300 million years before that, give or take, the land space that became Colorado had been episodically submerged beneath swamps and seas and ancestral mountain ranges. Around 70 million years ago tectonic shifts in the plates of the earth’s crust slowly uplifted the mountains we now call the <strong>Rockies</strong>. As they rose, wind, water, ice, and gravity wore them down. Wind and rivers deposited the material eroded from the mountains to form fertile soils on the <a href="/article/colorado’s-great-plains"><strong>Great Plains</strong></a> to the east. To the west, rivers carved the intricate canyons of the plateau country that extends throughout most of the Southwest, most notably the Grand Canyon. All this took a long time.</p>&#13; &#13; <p>The mountains also influenced the climate. As air masses ride the prevailing winds eastward across North America, little rain falls across much of the continent’s west. In Colorado the air masses rise up the western slope of the mountains, cooling as they do. Falling temperature lowers the amount of moisture the air can hold, and eventually rain or <a href="/article/snow"><strong>snow</strong></a> falls. The air masses continue eastward over the mountains but now carry scant moisture to drop on the plains. Today’s Colorado, then, can be divided into three parts, from east to west: plains, mountains, and plateau. The mountains are wet; the plains and plateau are dry. The mountains have forests, the plateau desert scrublands, and the plains grasslands. Everywhere, <a href="/article/wetlands-and-riparian-areas"><strong>riparian zones</strong></a> (ecosystems along rivers) abound in living things. Higher elevations are generally cooler than lower ones, so ecological zones transition as the altitude rises.</p>&#13; &#13; <p>Much of Colorado’s human history has flowed from these simple climatic, topographical, and biological arrangements. The first people to come to the place we will anachronistically call Colorado—at least 13,000 years ago—shaped their lives to this environment. Some of the oldest archeological sites in North America lie along Colorado’s <a href="/article/front-range"><strong>Front Range</strong></a> at places like <a href="/article/lindenmeier-folsom-site"><strong>Lindenmeier</strong></a>, north of <a href="https://coloradoencyclopedia.org/article/fort-collins"><strong>Fort Collins</strong></a>, and <a href="/article/dent-site"><strong>Dent</strong></a>, near Milliken. Such places indicate that the first peoples of Colorado were nomadic. Although plentiful, Colorado’s resources were dispersed. So people moved from place to place to gain the things they needed for life. Colorado’s landscape turned out to be ideal for this. From places like Lindenmeier and numerous other spots along the Front Range, people could access the resources of both the plains and mountains. With a day’s journey of thirty miles to the west into the mountains from grasslands to <a href="/article/beatrice-willard-alpine-tundra-research-plots"><strong>alpine tundra</strong></a>, they could obtain <strong>bison</strong> meat, berries from riparian bushes, timber for <a href="/article/tipi-0"><strong>tipi</strong></a> poles, rock and wood for tools, and a vast array of plant and animal species for food, medicine, dye, and more. To access a similar variety of ecosystems by traveling north or south on the plains would have required them to cover hundreds or thousands of miles. Taking full advantage of the resources that Colorado’s environment provided, these first Coloradans and their successors until the sixteenth century integrated themselves thoroughly into the land and lived well.</p>&#13; &#13; <p>The newcomers who began arriving in the seventeenth century revolutionized land use in Colorado. The changes got underway with the first arrivals of European explorers and traders. They brought <strong>horses</strong> and firearms, which changed the way the peoples there lived, how they used the environment, and much else about the cultures. Horses and firearms also made the plains a much more ecologically hospitable place by allowing people to tap the previously inaccessible energy sources of grass and gunpowder. Historian Elliott West has observed that by riding horses, which could consume and use the calories stored in grasses, mounted Plains Indians became radically more powerful organisms than their predecessors on foot. New energy sources meant new economic opportunities through hunting, trade, and raiding, luring <strong>Lakotas</strong>, <strong>Cheyennes</strong>, and <strong>Arapahos</strong> from the western Great Lakes region and the eastern Dakotas, <strong>Pawnees</strong> and <strong>Wichitas</strong> from the eastern prairies, and <strong>Kiowas</strong>, <strong>Comanches</strong>, and others from the mountains onto the Great Plains in the eighteenth century. Three hundred years after Columbus’s landing initiated a long period of population decline for many North American Indian cultures, the Great Plains actually saw an increase in people, and its inhabitants gained ever more control over their environment.</p>&#13; &#13; <p>The next phase of Colorado history began in 1858 with the <a href="/article/colorado-gold-rush"><strong>Colorado Gold Rush</strong></a> and was characterized by labor. Miners were not the first to rearrange the landscape. As we shall see, Indians had also. Beginning in the 1820s, traders and trappers had depleted mountain watersheds of <a href="/article/beaver"><strong>beavers</strong></a> and other fur-bearing animals. And <strong>Hispano</strong> settlers in the <a href="https://coloradoencyclopedia.org/article/san-luis-valley"><strong>San Luis Valley</strong></a> in the 1850s began diverting water for agriculture and domestic use. Mining, however, applied unprecedented amounts of human labor to the land and transformed local landscapes at speeds and scales rarely, if ever, previously accomplished by humans in Colorado. In their thirst for gold, newcomers to Colorado tunneled into the earth, washed away hillsides, diverted streams, and cut down trees. They invested their muscle energy, and that of their animals and eventually their machines, in a dogged quest to alter nature to make it produce wealth. Over the next century, <strong>mining </strong>remained a primary driver of the Colorado economy and re-shaper of the earth, as gold fever gave way to booms in silver, <strong>coal</strong>, and ultimately even <a href="https://coloradoencyclopedia.org/article/uranium-mining"><strong>uranium</strong></a>, among other valuable minerals.Mining launched large-scale modification of the environment, but Coloradans extended the practice of laboring to make the land more conducive to habitation and wealth accumulation. Railroad builder and city founder <a href="/article/william-jackson-palmer"><strong>William Jackson Palmer</strong></a> and his fellow entrepreneurs connected natural resources to supply centers and consumers to make Colorado’s abundance accessible and marketable. Farmers introduced new crops and figured out how to make money from local species, such as <a href="/article/sunflowers"><strong>sunflowers</strong></a>. Agriculture scraped parcels clean of all native organisms and replaced them with new ones: domesticated animals and crop plants. Engineering projects moved <a href="/article/water-colorado"><strong>water</strong></a> from places where it was plentiful to places where it was needed but scarce, thus undoing some of the age-old distinction between the wet <a href="/article/western-slope"><strong>Western Slope</strong></a> and the dry eastern third of the state.</p>&#13; &#13; <p>In 1938 northern Colorado voters agreed to tax themselves to move some of the <a href="/article/colorado-river"><strong>Colorado River</strong></a> basin’s copious waters east over the continental divide for use on farms and cities of the Front Range and plains. Other areas of the Front Range made similar moves. These and other enterprises to remake Colorado’s landscape generated enormous wealth. A few people, like Palmer, made grand fortunes, but even most ordinary Coloradans saw their material comfort improve in significant ways. Grocery stores, coal-heated homes, mail order catalogs, municipal water and sewage systems, and travel by train and then by automobile turned the daily labor of meeting basic needs for food, water, shelter, clothing, and movement into quicker and easier tasks.</p>&#13; &#13; <p>Material comfort changed how Coloradans thought about their environment. Mountains were no longer forbidding places, full of dangers from weather, animals, hunger, and injury. They were places of adventure and excitement and scientific discovery. The western deserts were no longer barren wastes but beckoning places of spiritual renewal and human antiquity. Rivers were no longer liquid gold, to be diverted and redirected to water thirsty croplands on the plains or in the <a href="/article/grand-valley-irrigation"><strong>Grand Valley</strong></a> but were thundering waves of nature’s majesty, to be admired and <strong>rafted</strong> for thrill or sanctuaries for escaping the bustle of urban life.  Former subsistence activities like hunting and fishing were now undertaken for sport. Once people’s labor had obtained material security for them, old environmental difficulties were reimagined as beauty, knowledge, and play.</p>&#13; &#13; <p>While many dates for this transformation might be chosen, one decisive one is 1955, when Coloradans joined Americans across the nation in pressuring Congress to reject the proposed <a href="/article/echo-park-dam-controversy"><strong>Echo Park Dam</strong></a> in <a href="/article/dinosaur-national-monument"><strong>Dinosaur National Monument</strong></a> on the grounds that the scientific, recreational, and aesthetic value of the park on the <strong>Colorado Plateau</strong> exceed the value that impounding water would yield. The nationwide effort to block the construction of this Colorado dam announced that leisure would sometimes trump labor in Coloradans’ decisions about how to interact with the land. Similarly, Colorado voters rejected the <a href="/keyword/1976-winter-olympics"><strong>1976 Winter Olympics</strong></a>, largely on environmental grounds, making <a href="/article/denver"><strong>Denver</strong></a> the first and only city in the world to have secured an Olympic bid and then turned it down. Coloradans also rebuffed the proposed <strong>Two Forks Dam</strong> on the Platte River for similar reasons.</p>&#13; &#13; <p>Throughout the twentieth century and into the twenty-first, organizations like the <a href="https://coloradoencyclopedia.org/article/san-luis-valley-ecosystem-council"><strong>San Luis Valley Ecosystems Council</strong></a> and the <a href="/article/clear-creek-canyon-0"><strong>Clear Creek Land Conservancy</strong></a> have encouraged stewardship of Colorado’s natural environment, while others like the <a href="/article/colorado-mountain-club"><strong>Colorado Mountain Club</strong></a> have promoted outdoor recreation in the state and made tourism a staple of the economy. Institutions such as the <a href="/article/denver-museum-nature-science-0"><strong>Denver Museum of Nature and Science</strong></a>, the <strong>Center of the American West</strong>, and the <a href="/article/colorado-foundation-water-education"><strong>Colorado Foundation for Water Education</strong></a> have made the state’s environment the object of intellectual and educational inquiry and stimulating public debate. Skiing, hiking, hunting, rafting, camping, and climbing grew in popularity through the second half of the twentieth century. Visitation at Colorado’s national parks and monuments, such as <a href="/article/rocky-mountain-national-park"><strong>Rocky Mountain National Park</strong></a>, <a href="/article/colorado-national-monument"><strong>Colorado National Monument</strong></a>, and<strong> <a href="/article/great-sand-dunes-national-park-and-preserve">Great Sand Dunes National Park</a></strong> soared, as did use of local preserves like the <a href="/article/denver-mountain-parks"><strong>Denver Mountain Parks</strong></a>. None of these thrilling activities, however, would been have been enjoyed by people who traveled on foot or hunted or farmed to feed themselves. For those kinds of people, the outdoors was not “great”; it promised daunting labor. Although Coloradans continued to labor, farm, mine, and frack, for most members of Colorado’s affluent society of the twentieth century, the outdoors increasingly meant leisure.</p>&#13; &#13; <p>Colorado’s environmental history, then, can be segmented into three broad periods. From at least 13,000 years ago or so, until the mid-nineteenth century, land influenced most aspects of human life, albeit with some notable exceptions. For the century after that, however, Coloradans dramatically increased their capability of reshaping the land to their liking through labor. So successful were they that they freed up disposable time and wealth to spend on having fun. Rocky Mountain National Park set visitation records in 2015, indicating that the era of leisure continues for the time being. This chronology of land shaping people, people re-shaping land, and eventually recreating in the land is simple and elegant. It explains a lot. It is not, however, the whole story.</p>&#13; &#13; <h2>Snapshots</h2>&#13; &#13; <p>Although revealing, the timeline’s neat division of time periods obscures the ways that land, labor, and leisure coexisted, overlapped, bled into each other, and often shaped society through their interactions with one another. Let’s go back and take another look at those <a href="/article/paleo-indian-period"><strong>Paleo-Indians</strong></a> who arrived so long ago. We know they survived by hunting mammoths, bison, and other megafauna, at the mercy of the environment more so than any subsequent people to walk the ground in North America. But they did so not only for subsistence, but for aesthetics. Ornamental beads, awls, and needles for manufacturing and decorating clothing indicate that they appreciated splendor and bothered to make beautiful things. Life was not just one big buffalo hunt. And while the land made bison, we also know that the Indians did too (and <a href="/article/rocky-mountain-elk"><strong>elk</strong></a>, deer, and other quarry). For example, they burned the land to promote grassy habitats attractive to species they hunted and to ensure a plentitude of game. Or consider the peoples of the Four Corners area who, around 800 CE, erected reservoirs and channels to water their crops in an arid land. Later, they also constructed elaborate towns and built roads to <a href="/article/chaco-canyon"><strong>Chaco Canyon</strong></a> and elsewhere. Clearly, Indians invested energy to alter the land and make it better fit their needs. Such snapshots reveal that they were people not only of the land, but of labor and leisure as well.</p>&#13; &#13; <p>Another telling moment of simultaneity among land, labor, and leisure, played out in the 1860s and 1870s in the valleys below <a href="/article/longs-peak"><strong>Longs Peak</strong></a>. In 1859 <strong>Joel Estes</strong> brought his family to the basin that would later bear his name. At first he tried to ranch but found the land—cold, snowy winters, short growing seasons, the burdens of clawing through snowdrifts to expose grass for hungry stock—made his efforts difficult and the profits small. So he returned to an age-old form of labor that human beings had practiced in Colorado for more than 13 millennia. He hunted—but he added an industrial twist. He and his family consumed little of the fruits of the chase themselves, instead hauling it to cities and mines to the south, where it sold for high prices.</p>&#13; &#13; <p>While the Estes clan struggled to eke out a living more than 7,000 feet above sea level, <a href="/article/william-n-byers"><strong>William N. Byers</strong></a>, publisher of the <strong><em>Rocky Mountain News</em></strong>, arrived from Denver in 1864 looking for sport. Staying with the Estes family, he attempted to climb Longs Peak—for fun. He failed, but left the valley predicting it would one day be a leading pleasure resort. Two years later, Joel Estes took his family down to warmer, more profitable climes. The land had beaten him. Others like him would try their hands too, but soon it was evident that the best way to make a living in Estes Park was by catering to vacationers, people who labored elsewhere with sufficient success that they came to play at camping, hunting, hiking, fishing, and other things Joel Estes did just to get by.</p>&#13; &#13; <p>Material security came unevenly to Colorado. The Estes’s labored mightily but could not bend the land enough to their needs to turn a profit. At the very same time, however, Byers and many others—notably Lord Dunraven and <strong>Isabella Lucy Bird</strong>—already enjoyed warmth, security, and full bellies in their daily lives. Such dignitaries found the lives of folks like Estes quaint and appealing enough to want to vacation by doing similar things. If one could not profit by laboring in <strong>Estes Park</strong>, perhaps one could play. In the shadow of Longs Peak, labor and leisure developed not in sequence, but simultaneously and in interaction with each other.</p>&#13; &#13; <p>If the hard pioneer life obscured the leisure that was beginning to take root at the very same time, the reverse was true a century later. Leisure obscured labor. In the twentieth century people came to play in the Rockies, only dimly aware, if at all, of the labor that underwrote their leisure. Passengers in sumptuous rail cars moved across the landscape without breaking a sweat; not so, however, for the porters, waiters, maids, and janitors whose work created the sense of luxury the passengers enjoyed. Today, every car that zooms up <a href="/article/interstate-70"><strong>Interstate 70</strong></a> to the ski slopes is fueled by gasoline taken from distant ecosystems. Resort goers’ rooms are warmed and lighted by electricity from power plants supplied by the efforts of coal workers. Hikers and campers enjoy the comforts of light, insulated, water-repellant gear, and tasty and nutritious pre-packaged food made by factory workers far away from the sublime granite peaks. While rafting the whitewater of the Colorado or <strong>Arkansas</strong> rivers, toasting frosty fingers at a ski chalet, stalking elk in the forests, soaking in hot springs at the base of Mt. Princeton, and touring the <a href="/article/cliff-dwelling"><strong>cliff dwellings</strong></a> at <a href="/article/mesa-verde-national-park"><strong>Mesa Verde</strong></a>, Coloradans experience an overwhelming sense of excitement, beauty, and relaxation—leisure. But none of it is possible without a network of labor, often invisible, that provides the energy and materials that make such adventures feasible. After all, it’s no fun skiing if you have to ride a mule to the slopes and spend the day—and night—in soaked clothing. Petroleum, Gortex, Thinsulate, central heat, air conditioning, cell phone signals, and the people who make, move, and deliver such amenities are a necessity for recreation.

Bison are commonly and incorrectly referred to as "buffalo," which are Asian and African animals. North American bison have long grazed in Colorado and are a central part of the spiritual and physical world of Colorado’s Indigenous people.</p> <p>For millennia, vast herds of bison roamed the <a href="https://coloradoencyclopedia.org/article/colorado%E2%80%99s-great-plains"><strong>Great Plains</strong></a>, until their numbers declined almost to extinction in the nineteenth century due to overhunting. Since then, however, their significance in American culture and their importance as a keystone species for the natural environment of the plains have prompted conservation efforts and a modest population resurgence. Today, those efforts have resulted in several <a href="/article/bison-reintroduction"><strong>managed bison herds</strong></a>&nbsp;across Colorado. In 2016 President Barack Obama named the bison the National Mammal of the United States.</p> <h2>Biology</h2> <p>Bison are diurnal animals, meaning they are active during the day. Historically, bison had distinct seasonal behaviors. In the winter, the gregarious mammals moved in small groups to seek forage and shelter, and in the summer months, they consolidated into massive herds for breeding and to protect the young. A much smaller population of free-ranging bison today continues these seasonal movements.</p> <p>Female bison, called cows, reach sexual maturity at about two to four years and typically give birth to only one calf at a time. The bison’s relatively slow reproduction rate compounded their decline when they were overhunted during the late nineteenth century. Calves are weaned off their mother’s milk after about one year. Male bison, called bulls, reach peak mass at about five to six years of age. Most bison do not live past twenty years.</p> <h2>Bison-Shortgrass Relationship</h2> <p>The Great Plains is the largest biome in North America. The High Plains, a part of that biome that extends across northeast Colorado to the foot of the <a href="https://coloradoencyclopedia.org/article/rocky-mountains"><strong>Rocky Mountains</strong></a>, is an ideal environment for bison, the area’s keystone species. Bison have shaped the area to fit their needs. The shortgrass ecology of the High Plains consists of two primary types of grass, blue grama (<em>Bouteloua gracilis</em>) and buffalo grass (<em>Buchloë dactyloides</em>), both of which have shallow root systems and grow unimpeded by the aridity that characterizes the region. Bison themselves are selected for these dominant varieties based on the nutrition they provide and their tolerance to cyclical patterns of wet and dry years. The shortgrass provides bison with a crucial nutritional balance of protein and carbohydrates; as much as 90 percent of a bison’s diet consists of grasses and sedges.</p> <p>Further, the grazing of bison herds induces new growth for both blue grama and buffalo grass, while their droppings return critical fertilizer to the prairie soil. Their grazing patterns are more intentional than one would think, with herds returning to graze the same carefully selected areas. This symbiotic relationship is why bison have existed for many millennia on the High Plains and have long been a central resource for the people living there.</p> <h2>Bison and Indigenous Nations</h2> <p>Archaeological evidence from across Colorado confirms that bison were a staple food resource for people living in the region as far back as the <a href="https://coloradoencyclopedia.org/article/paleo-indian-period"><strong>Paleo-Indian period</strong></a> (more than 9,000 years ago). At the <a href="https://coloradoencyclopedia.org/article/jones-miller-bison-kill-site"><strong>Jones-Miller</strong></a> and <a href="https://coloradoencyclopedia.org/article/olsen-chubbuck-bison-kill-site"><strong>Olsen-Chubbuck</strong></a> Bison Kill Sites, which date to about 8,000 BCE, Paleo-Indians herded bison into gulches, killed them, and butchered the bodies. At these and other sites, pot sherds, projectile <a href="https://coloradoencyclopedia.org/article/fluted-points-0"><strong>points</strong></a>, and bone debris indicate that the people who populated the High Plains hunted bison in cooperative groups and used their quarry for food, clothing, tools, and other materials. At the Massey Draw site near <a href="https://coloradoencyclopedia.org/article/denver"><strong>Denver</strong></a>, the large number of bones and the existence of modified organic materials for use as tools suggest that the site was a bison-processing encampment in the Middle <a href="https://coloradoencyclopedia.org/article/archaic-period-colorado"><strong>Archaic Period</strong></a> (~3,000-1,000 BCE). Similar killing and butchering techniques continued on the plains for thousands of years.</p> <p>In addition to its functional role as a food source, the bison is spiritually vital to many Western Great Plains Indigenous people. The nations most commonly associated with Colorado—including the Arapaho, Cheyenne, and Nuche (<a href="http://www.coloradoencyclopedia.org/search/google/ute"><strong>Ute</strong></a>) people—all depended on the bison as a food source. They held, and still hold, the animals as an essential part of their physical and spiritual connection to the land. To the Arapaho, who call the bison <em>heneecee</em>, the animal provided food and shelter and was a key component of trade and commerce. The Cheyenne, who call the bison <em>hotoa’e</em> and hunted them in extended family units, traded meat and pemmican to the horticultural nations on the eastern Great Plains in exchange for corn and wild foods. In addition, the Nuche, who call the bison <em>coch</em> or <em>kucu</em>, left their mountain encampments each summer to hunt bison herds on the Great Plains. They hunted bison for their own needs as well as to establish trade with Spanish colonists, known as Ciboleros, who specialized in the trade of bison flesh at markets in New Mexico.</p> <p>Bison were the foundation of transactions among Indigenous groups and between Indigenous nations and Euro-American nations. In this way, the mammals’ abundance undergirded the more extensive networks of imperial commerce on the nineteenth-century plains, such as the <a href="https://coloradoencyclopedia.org/article/santa-f%C3%A9-trail-0"><strong>Santa Fé Trail</strong></a>. Bison meat, hides, and tallow (fat) were principal commodities on the Great Plains. The market forces that came to bear on the region eventually spelled disaster for the bison in Colorado.</p> <h2>The Market for Bison</h2> <p>A variety of market factors drove the exploitation of the bison, including flesh for consumption or storage and bone ash for making fertilizer or to neutralize acids and clarify sugar, wine, and vinegar. However, in the early decades of the nineteenth century, demand for bison pelts surpassed these other uses as the main driver of the animal’s decline. Stemming directly from the already-established <a href="https://coloradoencyclopedia.org/article/beaver"><strong>beaver</strong></a> pelt trade, the bison robe market became dominant as beaver became rarer in the mountains and High Plains.</p> <p>The earliest American engagement with the bison robe market occurred in the early nineteenth century at <a href="https://coloradoencyclopedia.org/article/nineteenth-century-trading-posts"><strong>trading posts</strong></a> along overland trails. <a href="https://coloradoencyclopedia.org/article/bents-forts"><strong>Bent’s Fort</strong></a>, on the Arkansas River in what is now <a href="https://coloradoencyclopedia.org/article/otero-county"><strong>Otero County</strong></a>, was a well-known fur-trading post and commercial hub. There, white traders exchanged flour, firearms, textiles, and liquor for bison robes prepared by the Cheyenne, Arapaho, and other Indigenous peoples. In tandem with intensifying resource competition between bison and the growing herds of horses used to hunt them, the massive demand for robes contributed to a decline in bison, as Indigenous people were incentivized to overhunt the animal. By the 1850s, the decline in the robe market shuttered many of the fur-trading forts in Colorado, and Indigenous people who relied upon the once-innumerable resource began to starve and relocate as herds diminished.</p> <p>Several forces combined to keep bison numbers on a downward trajectory throughout the mid-nineteenth century. Increasing numbers of American colonists crossing the plains on overland trails used bison as a food source. The Comanche overhunted bison to sustain their raiding-and-trading empire and built huge horse herds that competed with the bison for grazing territory.</p> <p>As railroad tracks were laid across eastern Colorado during the 1870s, bison migration patterns were affected, and train strikes began killing bison who wandered across tracks. An increasing number of cattle and other ranch animals and the increasing amount of acreage put under cultivation reduced bison’s access to vital shortgrass prairie, and <a href="https://coloradoencyclopedia.org/article/irrigation-colorado"><strong>irrigation</strong></a> ditches bisected their grazing spaces. Droughts, <a href="https://coloradoencyclopedia.org/article/wildfire-colorado"><strong>wildfire</strong></a><strong>s</strong>, blizzards, and disease contributed significantly to the diminishing number of bison in Colorado and the broader Great Plains, as did the forced removal of Indigenous people who had previously managed the herds and held bison in higher regard than newly arriving colonists. On top of all that, tanners developed a new method for creating bison leather in the early 1870s, creating an insatiable demand for hides. By the 1880s, bison had been nearly hunted out of existence on the High Plains.</p> <h2>Saving a Species: Bison in the Twentieth Century</h2> <p>At the turn of the twentieth century, the bison underwent a transformation in the minds of many non-Indigenous Americans. For decades, hunting of the animals had been encouraged to weaken Indigenous nations and make way for the so-called progress of railroads, farming, and ranching in the West. With the conquest of the region complete, however, many Americans began to see both the bison and Indigenous people as symbols of a disappearing mythical frontier, and they became nostalgic about these symbols.</p> <p>Perhaps the best example of this change in sentiment is that of <a href="https://coloradoencyclopedia.org/article/william-f-%E2%80%9Cbuffalo-bill%E2%80%9D-cody"><strong>William F. “Buffalo Bill” Cody</strong></a>, an army veteran who hunted bison for the Kansas-Pacific Railroad and the US Army only to make the animals an important part of his subsequent “Wild West” shows that celebrated the American frontier. Cody’s shows were immensely popular and gave bison staying power as symbols of a romanticized American West. Cody, who first helped kill the bison and then helped spur a national lamentation of their loss, is now buried on Lookout Mountain, near Golden, not far from where a reintroduced bison herd roams.</p> <p>Later, in 1934, the <strong>University of Colorado</strong> (CU) adopted the name “Buffaloes” to represent its sports programs and campus community, further tying the bison to the lives of contemporary Coloradans. The mascot was chosen due to a national naming contest by CU’s student newspaper, <em>Silver &amp; Gold</em>. Boulder resident A. J. Dickson was the first to submit the name “buffaloes.” For the first football game of the 1934 season, CU students paid twenty-five dollars to have a bison calf on the sidelines (it is not known where the calf was taken from, though it likely came from Genesee Park). Since 1967 CU has had a live female bison, nicknamed “Ralphie,” lead the football team onto the field at home games.</p> <p>In Colorado, conservation of the keystone species has been in progress since the early twentieth century. Beginning in 1908, the city of Denver rounded up a herd of eighteen bison for conservation. The Denver herd lived on the prairie of <a href="https://coloradoencyclopedia.org/article/city-park"><strong>City Park</strong></a> and the <a href="http://www.coloradoencyclopedia.org/article/denver-zoo"><strong>Denver Zoo</strong></a>, but as the herd grew, its home moved to a larger site at <a href="https://coloradoencyclopedia.org/article/genesee-park"><strong>Genesee Park</strong></a> in 1914 and expanded to <a href="https://coloradoencyclopedia.org/article/daniels-park"><strong>Daniels Park</strong></a> in 1938. The city of Denver and the Denver Zoo continue to manage the bison herd, occasionally gifting bison to the Cheyenne, Arapaho, Ute, and other Indigenous nations with strong cultural ties to the animals. Collectively, these efforts protect the region’s biodiversity, support the recovery of the species, acknowledge Indigenous nations as equal partners in their protection, and provide the people of Colorado the opportunity to engage with one of their region’s most important species.</p> <h2>Today</h2> <p>Bison reintroduction programs continue in Colorado, and the state herds have increased significantly in number and physical health. A short distance from Denver, Coloradans can view the bison herd at <a href="https://coloradoencyclopedia.org/image/rocky-mountain-arsenal"><strong>Rocky Mountain Arsenal</strong></a>. In <a href="https://coloradoencyclopedia.org/article/golden"><strong>Golden,</strong></a> the overlook at exit 254 off <a href="http://www.coloradoencyclopedia.org/article/interstate-70"><strong>Interstate 70</strong></a> allows observation of the Genesee Park herd. In <a href="https://coloradoencyclopedia.org/article/larimer-county"><strong>Larimer County</strong></a>, bison viewing areas at Soapstone Prairie Natural Area and Red Mountain Open Space enable visitors to see a herd with genetic links to some of the last remaining wild bison in the Yellowstone region. The state of Colorado, the federal government, and many Indigenous nations continue to prioritize the reintroduction, study, and management of the prairie’s keystone species and the country’s national mammal.</p> </div> <!-- END OUTPUT from 'themes/custom/encyclopedia/templates/field/field--node--encyclopedia-article.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME

It studies the connectivity of cold desert ecosystems, like the ones found on <a href="http://www.coloradoencyclopedia.org/article/rocky-mountains"><strong>Rocky Mountain</strong></a> peaks. INSTAAR was one of the country's first prominent ecological research programs and found early success in the mid-twentieth century. Since the mid-1970s, INSTAAR has shifted its mission to study how climate change affects the high-altitude tundra and how these seemingly small changes in Colorado may affect similar ecosystems globally.</p>&#13; &#13; <h2>Early History</h2>&#13; &#13; <p>The idea for an alpine research organization was devised in 1946 when John Marr, professor of biology at the University of Colorado, took a group of students to the school’s <strong>Science Lodge </strong>on Niwot Ridge, near the Indian Peaks west of <a href="http://www.coloradoencyclopedia.org/article/boulder"><strong>Boulder</strong>,</a> to study winter plant ecology. While eating sandwiches and discussing dwarven plants, Marr and his students were overcome by a blizzard. The stormy picnic inspired Marr and his students to establish measurement stations around the lodge to record wild weather fluctuations and to gather more data about the alpine tundra. INSTAAR was born.</p>&#13; &#13; <p>From the outset, INSTAAR was concerned with the global connectivity of tundra environments but had difficulty fulfilling its mission due to constant budget constraints. John Marr and his team aimed to record data in both Colorado and the Canadian Arctic, where he previously studied tree distribution and soil composition. But the institute could only get enough cash for a seasonal stint in Ungava Bay in Nunavut, Canada, in 1948. As he struggled to find funding for longer Arctic research trips, Marr insisted that the team could facilitate near-identical studies in Colorado, where high <a href="https://coloradoencyclopedia.org/.../beatrice-willard-alpine-tundra-research-%20plots"><strong>alpine tundra</strong></a> ecosystems mirrored Arctic conditions.</p>&#13; &#13; <p>Neither CU nor the federal government was interested in funding a new biological database to survey conditions in Niwot because the research had no immediate promise of profit or Cold War-era military application. In response to the government’s data priorities, Marr advertised his program as an opportunity for the Army’s Quartermaster General office to test cold weather equipment. The Quartermaster General office took the bait and funded Marr’s alpine ecology field research on the condition that he and his students test military gear, such as coats, gloves, and even tank-like vehicles, while they collected data.</p>&#13; &#13; <p>The Institute of Arctic and Alpine Ecology was officially formed in 1951 (the catchy acronym INSTAAR was not adopted until the mid-1960s). Within the year, Marr and his students established sixteen Environmental Analysis Stations around Niwot Ridge, at elevations ranging from 5,500 to 13,000 feet.</p>&#13; &#13; <p>Throughout the 1950s and early 1960s, INSTAAR began to garner a reputation for its local accessibility, wide-ranging interdisciplinary research, and educational fieldwork opportunities. Meanwhile, Marr’s students conducted research of their own. <a href="https://coloradoencyclopedia.org/article/beatrice-willard"><strong>Beatrice Willard</strong></a>, a student of Marr’s in the late 1950s, was among the first to study sensitive alpine tundra environments along <a href="https://coloradoencyclopedia.org/article/trail-ridge-road"><strong>Trail Ridge Road</strong></a> in <a href="https://coloradoencyclopedia.org/article/rocky-mountain-national-park"><strong>Rocky Mountain National Park</strong></a>.</p>&#13; &#13; <h2>Shift in Focus</h2>&#13; &#13; <p>The 1960s and early 1970s marked a shift in the University of Colorado’s emphasis on scientific research. In 1967 CU geography professor Jack Ives<strong>,</strong> former director of the Sub-Arctic Research Laboratory at McGill University in Québec, Canada, took on Marr’s position at INSTAAR. CU hired Ives as a way to attract other world-renowned cold temperature researchers and expand CU’s growing reputation as a scientific research behemoth. Ives took full advantage of the university’s renewed investment by finally cosigning yearly research trips to Baffin Island and Labrador in the Canadian Arctic. This solidified a permanent polar presence for the institution.</p>&#13; &#13; <p>Ives not only stretched INSTAAR’s geographic range but also helped make a compelling case for why Colorado’s ecology mattered globally. INSTAAR’s two-decade history of long-term ecological research in the alpine tundra earned Niwot Ridge a tundra biome site designation for the International Biological Program (IBP) in 1971. The program collected data about ecosystems around the world to understand how they might interact with one another on a global scale.</p>&#13; &#13; <p>The 1960s also saw INSTAAR’s first major project emphasizing the functional application of tundra research for state and national interests. In 1969 INSTAAR partnered with <strong>Colorado State University</strong> (CSU) to research the effects of cloud seeding in the <a href="http://www.coloradoencyclopedia.org/article/san-juan-mountains"><strong>San Juan Mountains</strong></a>. The <a href="https://coloradoencyclopedia.org/article/bureau-reclamation-colorado"><strong>Bureau of Reclamation</strong></a> funded the study and assessed how animals and plants reacted to higher precipitation and delayed snowmelt, in addition to how the active trigger chemical in seeding—iodide, toxic to both animals and humans—affected those life systems. CSU focused on collecting data on forest ecosystems, while INSTAAR tackled similar research in the alpine tundra.</p>&#13; &#13; <p>The operation's goal was to build on previously successful cloud-seeding experiments toward adding more water to the Upper <a href="http://www.coloradoencyclopedia.org/article/colorado-river"><strong>Colorado River</strong></a> Basin. The bureau hoped that weather modification would be the ultimate step in reconfiguring the western landscape against the threat of <strong>drought</strong> and the region’s growing population. INSTAAR and CSU took on this initiative despite knowing that the experiments might elevate levels of silver iodide in the Basin. The data ultimately reflected this worst-case scenario, and the program was shut down when toxicity in the region increased.</p>&#13; &#13; <p>INSTAAR’s work with CSU on the cloud seeding project demonstrated that it could successfully collaborate with other institutions. This led to an additional research partnership with the University of Washington, and the Army Cold Regions Research and Engineering Labs in New Hampshire focused on <strong>avalanche</strong> research. These seven years brought considerable fame to INSTAAR in the academic community while highlighting additional applications of its tundra research.</p>&#13; &#13; <h2>Role of Climate Change</h2>&#13; &#13; <p>Since the 1970s, INSTAAR has increasingly focused on atmospheric research and the impact of climate change. This was partly thanks to an invigorated <strong>environmental movement</strong> and increasing recognition of ecology’s role in human health and wellbeing. In response to this movement, the federal government launched the Long Term Ecological Research (LTER) initiative, which awarded funding to long-term data-collection projects. The National Science Foundation began searching for sites in 1978, and by 1980 Niwot Ridge became one of the first locations to receive an LTER designation.</p>&#13; &#13; <p>In 1992 the University of Colorado, in partnership with the United States Geological Survey (USGS), was awarded a second LTER site in the McMurdo Dry Valleys, Antarctica. INSTAAR’s inclusion in the LTER signaled a shift from national security applications to the scientific investigation of the effects of climate change.</p>&#13; &#13; <p>Much of the USGS’s work in Antarctica involved drilling for ice cores to study biological and environmental conditions. The INSTAAR-USGS partnership in Antarctica culminated in the creation of the National Ice Core Lab in 1993. This was housed in the USGS federal center in <a href="http://www.coloradoencyclopedia.org/article/denver"><strong>Denver</strong></a> and administered by INSTAAR. The goal of the Ice Core Lab is to collect, house, and distribute ice cores. Management of the lab has since been transferred from INSTAAR to the University of New Hampshire. Studying ice cores helps researchers understand historic chemical fluctuations in the atmosphere, such as carbon dioxide levels, providing insight into today’s atmospheric composition.</p>&#13; &#13; <h2>Recent Activity</h2>&#13; &#13; <p>Since the 1980s, INSTAAR has pioneered several landmark observations and models regarding tundra and polar science. The Niwot LTER, for instance, has determined that the tundra is becoming incrementally wetter and has created several models articulating carbon and nitrogen cycling in the tundra. Researchers at the McMurdo site have studied how changing stream flows due to climate change have affected delicate microbial environments. In 2012 the INSTAAR team in Antarctica also worked with NASA to study microbiology in the context of climate change and potential extraterrestrial organisms. Research in both regions is ongoing and has been a critical resource for other federal scientific agencies, including the National Oceanic and Atmospheric Administration (NOAA), the National Center for Atmospheric Research (NCAR), and other organizations. </p>&#13; &#13; <h2>Legacy</h2>&#13; &#13; <p>INSTAAR’s decades of ecological research have helped scientists understand how global environments are connected. INSTAAR continues to advance this mission, making its work more accessible to the public through educational programs at Mountain Research Station and other trips that invite students into the field. INSTAAR has played an instrumental role in working to help Colorado scientists and communities understand how to mitigate and prepare for the effects of climate change.</p>&#13; </div>&#13; </div>

It is one of the only tree species to grow on Colorado’s <a href="https://coloradoencyclopedia.org/article/colorado%E2%80%99s-great-plains"><strong>Great Plains</strong></a>, which made it an important source of forage, fuel, timber, and medicine for Indigenous people, <a href="https://coloradoencyclopedia.org/article/terminology-latino-experience-colorado"><strong>Hispanos</strong></a>, and white immigrants. The cottonwood gets its name from the millions of cotton-like seeds that female trees release each spring.</p> <h2>Description</h2> <p>Cottonwoods are tall, deciduous trees commonly found along riverbanks and other high-moisture areas, with broad leaves and dark gray bark. They thrive at altitudes of 3,500 to 6,500 feet and reach a maximum height of around 190 feet.</p> <p>Seeding and sprouting are the cottonwood’s two major avenues of reproduction. Cottonwoods are dioecious, meaning individual trees are either male or female. Females grow necklace-like strings of seedpods that release millions of white, cottony seeds into the air, typically in June. Males grow purple flowers. Like their mountain-dwelling cousins the <a href="https://coloradoencyclopedia.org/article/aspen-trees"><strong>aspen</strong></a>, cottonwoods are members of the poplar family, but unlike the aspen, cottonwoods do not produce clone trees from a single root system. However, like other poplars, cottonwoods will readily resprout if broken or cut down—a trait that has coevolved with breaking and browsing animals such as <a href="https://coloradoencyclopedia.org/article/beaver"><strong>beaver</strong></a>, <a href="https://coloradoencyclopedia.org/article/bison"><strong>bison</strong></a>, and <strong>horses</strong>.</p> <p>Cottonwoods live just over 100 years—a fairly short lifespan for a tree. Sometimes large branches and the inner core of the tree will die before the rest of it, contributing to its common half-dead appearance. Cottonwoods in this condition represent a hazard, as branches can break and fall at any moment.</p> <h2>Ecology</h2> <p>As the vertical sentinels of the largely horizontal plains, cottonwoods provide habitat and food for many animals, from bison to birds, squirrels, and ponies. Eagles, blue jays, magpies, and woodpeckers are among the avian species that find respite in the cottonwood’s branches. Beaver stimulate cottonwood growth by gnawing down trunks, and bison, horses, and ponies eat the tree’s bark. Smaller trees, including willow and box elder, and shrubs thrive in the shade produced by the cottonwood.</p> <h2>Indigenous Culture</h2> <p>Indigenous people who lived on the plains and in the southwest part of the state—including the <strong>Apache</strong>, <strong>Arapaho</strong>, <strong>Cheyenne</strong>, <strong>Comanche</strong>, and <strong>Navajo</strong>—revered the cottonwood as a source of medicine and for its many practical uses, especially forage and food for horses. Sun Dance artifacts were carved from cottonwood. Perhaps the most famous grove of cottonwoods in the state was the Big Timbers, a thick stand along the <a href="https://coloradoencyclopedia.org/article/arkansas-river"><strong>Arkansas River</strong></a> in southeast Colorado. In the early 1800s, the Cheyenne and Arapaho fought the Comanche and Kiowa for control of the sacred grove, with all four nations brokering a peace in 1840. Meanwhile, an old, thick cottonwood along the <a href="http://www.coloradoencyclopedia.org/article/cache-la-poudre-river"><strong>Cache la Poudre River</strong></a> near present-day <a href="https://coloradoencyclopedia.org/article/fort-collins"><strong>Fort Collins</strong></a> served as a Council Tree, a meeting spot for a local band of Arapaho led by <a href="https://coloradoencyclopedia.org/article/teenokuhu-friday"><strong>Teenokuhu</strong> <strong>(Friday)</strong></a>.</p> <p>In one Arapaho story, a girl named Sapana climbs a tall cottonwood into the sky itself, where she is then put to work skinning bison hides by an old man who takes the form of a porcupine. The girl is helped back to earth by a buzzard and a hawk. In return for their help, the Arapaho always left at least one bison carcass for the buzzards and hawks after their hunts.</p> <h2>Hispano Culture</h2> <p>Cottonwood trees were also a prominent part of early Hispano culture. In southern Colorado’s <a href="https://coloradoencyclopedia.org/article/hispano-settlement-purgatoire-valley"><strong>Purgatoire</strong></a> valley, members of the Catholic Penitente Brotherhood carved <em>santos</em>, or holy images, into cottonwood roots and trunks. In the <a href="http://www.coloradoencyclopedia.org/article/san-luis-valley"><strong>San Luis Valley</strong></a>, where permanent Hispano settlements began in the 1850s, cottonwood beams supported adobe buildings, including the many <a href="https://coloradoencyclopedia.org/search/google/iglesia"><strong><em>iglesias</em> and <em>capillas</em></strong></a>—churches and chapels—established across the valley. The town and <a href="http://www.coloradoencyclopedia.org/article/alamosa-county"><strong>county</strong></a> of <strong>Alamosa</strong> were named after the Spanish word for cottonwood grove.</p> <h2>American Culture</h2> <p>In 1807 American explorer <a href="http://www.coloradoencyclopedia.org/article/zebulon-montgomery-pike"><strong>Zebulon Pike</strong></a> built his <a href="https://coloradoencyclopedia.org/article/pike%E2%80%99s-stockade"><strong>stockade</strong></a> in the San Luis Valley out of cottonwood logs. Other whites quickly realized the importance of cottonwoods when they began crossing the plains to Colorado during the <a href="/article/colorado-gold-rush"><strong>Gold Rush of 1858–59</strong></a>. In addition to being the only fuel aside from bison droppings, cottonwoods provided shelter and food for draft animals and acted as guideposts for immigrant parties who needed to stick to the river paths, lest they become lost in the monotonous landscape of the plains. When immigrants reached the area of present-day <a href="https://coloradoencyclopedia.org/article/denver"><strong>Denver</strong></a>, they found building materials scarce; as such, the first house in what became Denver City, on today’s <a href="http://www.coloradoencyclopedia.org/article/larimer-square"><strong>Larimer Street</strong></a>, was built of “round cottonwood logs” and “roofed with earth.”</p> <p>One of the first editions of the <strong><em>Rocky Mountain News</em></strong>, printed on May 14, 1859, reflects white immigrants’ views of the cottonwood as part of the strikingly beautiful scenery of springtime along the eastern slope of the <a href="http://www.coloradoencyclopedia.org/article/rocky-mountains"><strong>Rocky Mountains</strong></a>:</p> <p style="margin-left:.5in;">The prairies are putting on their robes of green and the bright verdure of the cottonwood and alder contrasts beautifully with the dark sombre [<em>sic</em>] hue of the evergreen forests.</p> <p>White immigrants’ consumption of cottonwood groves only increased as more Americans traveled west over the ensuing decades. The depletion of this important resource, as well as the simultaneous and related decline of the bison, contributed to starving conditions among many Indigenous bands in the mid- to late nineteenth century.</p> <h2>Threats</h2> <p>Since they are water-loving trees, cottonwoods are especially susceptible to drought. Millions died during the 1930s drought that contributed to the <a href="https://coloradoencyclopedia.org/article/dust-bowl"><strong>Dust Bowl</strong></a>, and many more could be lost in the twenty-first century as a warming <a href="http://www.coloradoencyclopedia.org/article/colorado-climate"><strong>climate</strong></a> increases drought frequency and length. In addition, dams built since the beginning of the twentieth century have lowered flow rates in the <a href="http://www.coloradoencyclopedia.org/article/south-platte-river"><strong>South Platte</strong></a>, Arkansas, and other rivers, leading to a decline in cottonwood reproduction.</p> </div> <!-- END OUTPUT from
