Hovenweep National Monument, located in eastern Utah along the Colorado border, is known for its stone masonry structures clustered around multiple canyons. To protect these unique archaeological resources, President Warren G. Harding established the monument on March 2, 1923. Hovenweep is composed of six individual units that encompass about 785 acres. Two of the units (Cajon and Square Tower) are in Utah. The remaining four units (Holly, Horseshoe-Hackberry, Cutthroat, and Goodman Point) are in Colorado.

Archaeologists believe that the Ancestral Puebloan people built most of the structures at Hovenweep. Based on tree-ring dates taken from roof beams, the structures were built during the Pueblo III period, between AD 1166 and 1277. During this time, people in the Four Corners area gathered in villages and work became specialized. One of those specialized jobs was stone masonry.  

The masons at Hovenweep were meticulous. They pecked, or formed, the local sandstone, creating buildings and towers in and around uneven surfaces. A variety of structures and shapes are represented at Hovenweep, including round and square towers, D-shaped buildings, and rectangular room blocks. Some of the buildings are found atop or within eroded portions of boulders. Others are located along the rims of drainages. Some of the buildings are single-story, while others have multiple stories. Some were built as homes, others as storage facilities or ceremonial rooms.

But the Pueblo III buildings do not represent the whole story at Hovenweep. Archaeologists have also found artifacts, rock art panels, and types of shelters that indicate these lands were also known to an earlier nomadic group called the Archaic people. They inhabited the area from about 6000 to 600 BC. They were followed by the horticulturalist Basketmaker people, from about 600 BC to AD 750. Then came the agricultural Ancestral Puebloans of the Pueblo II period, from AD 950 to 1150. After the Pueblo III period, when Hovenweep was built, the area was home to Protohistoric and Historic groups from AD 1600 to 1840.

Hovenweep was first known to Europeans in the mid- to late-1500s. Spanish explorers came through the region marking travel routes. In 1854 W. D. Huntington submitted what may be the first published report on Hovenweep to the editor of the Deseret News in Salt Lake City. William H. Jackson, a member of the Hayden Survey conducted between 1874 and 1877, came through the area to map and photograph the lands. It is believed that he was the first person to use the name “Hovenweep.” It was a word he had heard from native peoples, meaning “deserted valley.”

Located in eastern Utah near the Colorado border, Hovenweep National Monument is known for its ancient stone masonry structures situated around canyons. President Warren G. Harding established the Hovenweep National Monument on March 2, 1923. The monument is composed of six units. Together, they encompass about 785 acres. Cajon and Square Tower are in Utah. Holly, Horseshoe-Hackberry, Cutthroat, and Goodman Point are in Colorado.

Archaeologists believe that the Ancestral Puebloan people built Hovenweep. Tree-ring dates taken from wooden roof beams suggest that the structures were built during the Pueblo III period, from AD 1166 to 1277. During this time, people in the Four Corners area formed villages. More than 2,000 people lived in the area. Work became specialized, with masonry being one of these jobs.

The masons at Hovenweep were meticulous. They worked with sandstone to create buildings and towers. Uneven surfaces, even boulders, were used as the base of some buildings. Some of the stones were pecked, or shaped, into a specific form. Some were simply used in their original shape. Hovenweep has round and square towers, D-shaped buildings, and rectangular rooms. Some of the rock is so well-formed that it looks like brick. There are single- and multi-story buildings. There is even a three-story tower. These structures were homes, storage rooms, and ceremonial kivas.

The Pueblo III buildings are just part of the story of Hovenweep. Archaeologists have also found artifacts, rock art panels, and shelters. These artifacts show that the land was also known to an earlier nomadic people called the Archaic people. They lived from about 6000 to 600 BC. They were followed by the Basketmaker people, from about 600 BC to AD 750. Next came the agricultural Pueblo II Ancestral Puebloans, from AD 950 to 1150. In the centuries after the drought that ended the Pueblo III period, the area was home to ancestors of the Pueblo, Zuni, and Hopi peoples.

Hovenweep was first known to Europeans in the mid- to late-1500s. Spanish explorers came through the region. They marked travel routes. In 1854 Mormon settler W. D. Huntington submitted a report on the area for the Deseret News in Salt Lake City. It is likely the first published report on Hovenweep. William H. Jackson was a member of the Hayden Survey that came through the area between 1874 and 1877. The survey team mapped and photographed the lands. Jackson is believed to be the first to use the name “Hovenweep.” He had heard the word from native peoples. It means “deserted valley.”

Hovenweep National Monument is along the Utah-Colorado border. It is known for its ancient stone structures built around small canyons. President Warren G. Harding made it a national monument on March 2, 1923. Hovenweep has six units that cover about 785 acres.

The Ancestral Puebloan people built Hovenweep. It was built during the Pueblo III period (AD 1166–1277). During this time, people formed villages. Jobs became specialized. One of those jobs was building.

The masons at Hovenweep were very skilled. They used the local sandstone to create many kinds of buildings. Some are one story. Some are multi-storied. Some look like castles. The masons shaped some stones to look like bricks. Some stones are unshaped. The masons worked on uneven surfaces. Some buildings sit on top of boulders. The rooms are in many shapes. There are rectangular rooms, circular rooms, and D-shaped rooms. A building called Twin Towers has two turrets. One turret is round, but the other is square.

The Pueblo III buildings are just part of the story of Hovenweep. Archaeologists have also found artifacts, rock art panels, and shelters nearby. These show that the land was known to an earlier group. These people, called the Archaic people, were nomads. They moved around, living in different places. They lived at Hovenweep from about 6000 to 600 BC. They were followed by the Basketmaker people. They lived in the area from about 600 BC to AD 750. Next came the Ancestral Puebloans. This group lived there from AD 950 to 1150. Then came the Pueblo III peoples. They built Hovenweep. A drought ended the Pueblo III period. The buildings were abandoned. The area later became home to ancestors of the Pueblo, Zuni, and Hopi peoples.
