It was named for its distinctive wedge shape by the Garibaldi Park Board in 1932 in preference to Mount Vancouver, which had been submitted earlier.

Wedge's very high prominence is defined by the divide between the Green and Cheakamus Rivers at a locality at the south end of Alta Lake known as Tokum Corners.

To approach the South face parties must climb over the glacier to the West Couloir, across the bottom of it and up to the left.

[3] 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.
