Pryor Mountain Mustang

Horse

The Pryor Mountain Mustang is a substrain of Mustang considered to be genetically unique and one of the few strains of horses verified by DNA analysis to be descended from the original Colonial Spanish Horses brought to the Americas by the Spanish. They live on the Pryor Mountains Wild Horse Range located in the Pryor Mountains of Montana and Wyoming in the United States. They are protected by the Wild and Free-Roaming Horses and Burros Act of 1971 and managed by the Bureau of Land Management (BLM). Because of the unique genetic makeup of the Pryor Mountains Mustang herd, equine geneticist Dr. E. Gus Cothran concluded in 1992 that "the Pryor herd may be the most significant wild-horse herd remaining in the United States. Dr. D. Phillip Sponenberg, equine veterinarian at Virginia-Maryland Regional College of Veterinary Medicine, agreed, noting, "[These animals] don't exist anywhere else. This herd was the subject of the 1995 documentary film Cloud: Wild Stallion of the Rockies and its sequel, the 2003 documentary film Cloud's Legacy: The Wild Stallion Returns.
