Sofa Mountain is a 2,515-meter (8,251-foot) summit located in Waterton Lakes National Park, in Alberta, Canada.

It is situated 5.4 km (3.4 mi) east of Vimy Peak, and the nearest higher neighbor is Crypt Peak, 4.6 km (2.9 mi) to the southwest.

[1] Topographic relief is significant as the north aspect rises over 1,220 meters (4,000 feet) above Middle Waterton Lake in approximately six kilometers (3.7 mi).

Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.

[7] Based on the Köppen climate classification, Sofa Mountain has an alpine subarctic climate with cold, snowy winters, and mild summers.
