The peak's descriptive local name was reported in 1908 by the United States Geological Survey.

Based on the Köppen climate classification, Pyramid Peak is located in a subarctic climate zone with long, cold, snowy winters, and cool summers.

[4] Weather systems coming off the Gulf of Alaska are forced upwards by the Saint Elias Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall.

This climate supports small unnamed glaciers on its north and south slopes.

The months May through June offer the most favorable weather for viewing and climbing.
