The Red Desert is a high-altitude desert and sagebrush steppe located in the south-central portion of the U.S. state of Wyoming, comprising approximately 9,320 square miles (24,100 square kilometers). Among the natural features in the Red Desert region are the Great Divide Basin, a unique endorheic drainage basin formed by a division in the Continental Divide, and the Killpecker Sand Dunes, the largest living dune system in the United States. In the 19th century, the Oregon, California, and Mormon Trails crossed the Continental Divide at South Pass, just north of the Red Desert. Today, busy Interstate 80 bisects the desert's southern region while gas field roads cross the desert.
The majority of the Red Desert is public land managed by the Rock Springs and Rawlins field offices of the U.S. Bureau of Land Management (BLM). The region is rich in oil, natural gas, uranium, and coal. An estimated 84% of the Red Desert has been "industrialized" by oil and gas drilling or by mining operations and associated roads.[1]
The Red Desert supports an abundance of wildlife, despite its scarcity of water and vegetation. The largest migratory herd of pronghorn in the lower 48 states and a rare desert elk herd, said to be the world's largest, live in the desert.[2] Ponds fed by summer snowmelt attract a wide range of migratory birds such as ducks, trumpeter swans,[citation needed] and white pelicans.[citation needed] Herds of wild, free-roaming horses protected under the Wild Free-Roaming Horses and Burros Act of 1971 roam the area, despite roundups and population control efforts by the BLM. Bison were once common as well and their skulls and horns can occasionally be found there.
