Mount Donkin is located in Glacier National Park and is part of the Selkirk Mountains.

Mount Donkin is more notable for its steep rise above local terrain than for its absolute elevation.

Topographic relief is significant as the summit rises 1,840 metres (6,037 ft) above the Incomappleux River in 2.5 km (1.6 mi).

The nearest higher neighbor is Michel Peak on Mount Dawson, 1.89 km (1.17 mi) to the east.
