    With heights of up to 750 feet, the Great Sand Dunes in Alamosa County are the highest sand dunes in North America. They were formed around 12,000 years ago, as wind continuously blew sediment from the upper Rio Grande River westward across the San Luis Valley, piling it at the foot of the Sangre de Cristo Mountains.
