In western Colorado, wind and water have eroded what was once part of the Cretaceous North American Inland Sea to produce one of the most subtly arresting landscapes in the country. The Adobes are home to ancient marine fossil beds as well as deer, elk, pronghorn antelope, prairie dogs, badgers, coyotes, bobcats, red-tailed hawks and golden eagles. The area is currently under Wilderness Study Area designation, but lacks any kind of durable protection.
