Klapperhorn Mountain

It is the northernmost peak of the Selwyn Range,[1] which is a subrange of the Canadian Rockies.

Precipitation runoff from the peak drains north into the Fraser River.

Topographic relief is significant as the summit rises 1,400 meters (4,600 ft) above the Robson Valley in 2 km (1.2 mi).

The nearest neighbor is line parent Overlander Mountain, 2.0 km (1.2 mi) to the southeast.

[3] The mountain is a classic horn-shaped summit, which is notable for the frequency of its rockslides which are audible to campers and are a source of much curiosity and interest.
