Thor Peak is a 12,306-foot-elevation (3,751-meter) mountain summit located east of the crest of the Sierra Nevada mountain range in Inyo County, California.[3] It is situated in the John Muir Wilderness on land managed by Inyo National Forest. It is 12.5 miles (20.1 km) west of the community of Lone Pine, and 1.5 miles (2.4 km) east of Mount Whitney. Topographic relief is significant as it rises 3,937 feet (1,200 meters) above Whitney Portal in 1.5 mile. Hikers on the Mount Whitney Trail pass below the impressive south face of the peak.

Climate

According to the Köppen climate classification system, Thor Peak has an alpine climate.[4] 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). Precipitation runoff from this mountain drains east to Owens Valley via Lone Pine Creek.

Climbing

The first ascent of the summit was made by Norman Clyde, date unknown.[5]
