Stuffed Mountain Goat Head. The mountain goat (Oreamnos americanus), also known as the Rocky Mountain goat, is a large hoofed mammal endemic to North America. A subalpine to alpine species, it is a sure-footed climber commonly seen on cliffs and ice. The mountain goat inhabits the Rocky Mountains and Cascade Range and other mountain regions of the Western Cordillera of North America, from Washington, Idaho and Montana through British Columbia and Alberta, into the southern Yukon and southeastern Alaska. Despite its vernacular name, it is not a member of Capra, the genus that includes all other goats, such as the wild goat, Capra aegagrus, from which the domestic goat is derived.
