[1] Whitecap Mountain is notable for its steep rise above local terrain as topographic relief is significant with the summit rising over 1,300 metres (4,265 ft) above the Connel Creek valley in 2.5 kilometres (1.6 mi).

The mountain's local descriptive toponym was officially adopted on March 31, 1924, by the Geographical Names Board of Canada.

[4] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall.

As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall.

This climate supports three unnamed glaciers on the north, northwest, and east slopes of the mountain.
