A mountain goat along Sperry Glacier Trail, Glacier National Park, Montana, USA

The mountain goat (Oreamnos americanus, or Rocky Mountain Goat) is a large-hoofed mammal found only in North America. This even-toed ungulate is in the family Bovidae, in subfamily Caprinae (goat-antelopes) in the Oreamnos genus (but is NOT a true "goat"–Capra genus).
