Topographic relief is significant as the west aspect rises 2,900 feet (880 meters) above Goddard Canyon in 1.5 mile.

This geographical feature was named by the Sierra Club in 1938 in memory of one of their own, Peter Grubb (1919–1937), who made the first ascent of this peak in 1936.

[5] Peter died at Capri, age 18, while traveling on a bicycle tour of Italy.

[7] Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains.

As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift).
