Oscar Peak is more notable for its steep rise above local terrain than for its absolute elevation.

Topographic relief is significant as the summit rises 1,300 meters (4,265 feet) above Hadenschild Creek in 2 kilometers (1.2 miles).

[4] A geographic survey party so-named the peak after Mr. Olander as appreciation for the lodging he provided for them.

[6] 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.
