Calf Robe Mountain is a prominent summit on the Continental Divide in Glacier National Park, rising sharply above U.S. Highway 2 near Marias Pass and East Glacier Park. Named for Calf Robe, a Blackfeet man also known as Onistai'yi, it reflects a Blackfeet tradition in which he survived abandonment in enemy country after aid from a grizzly bear, a story linked to the Piikani taboo against killing hibernating bears. Officially adopted in 1940 after a 1939 submission, the mountain also embodies Glacier’s geologic history, having formed from ancient sedimentary rock shaped by the Lewis Overthrust, and remains a striking landmark where terrain, geology, and tradition converge.
