The remote peak is situated southwest of the head of the Beaver River and is set on the southern boundary of Glacier National Park.

Beaver Mountain is more notable for its steep rise above local terrain than for its absolute elevation.

Topographic relief is significant as the summit rises 1,600 meters (5,250 ft) above Butters Creek in 3 km (1.9 mi).

[7] The mountain's toponym was officially adopted on July 29, 1904, by the Geographical Names Board of Canada.

[6] The first ascent of the summit was made August 25, 1913, by Edward W. D. Holway, Ernest Feus and Christian Häsler, Jr.[8] Based on the Köppen climate classification, Beaver Mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.
