Volcanic Ridge

Volcanic Ridge is an ridge located in the Sierra Nevada mountain range in Madera County of northern California, United States. It is situated in the Ansel Adams Wilderness on land managed by Inyo National Forest. It is set in the Ritter Range, southeast of Mount Ritter, and approximately west of the community of Mammoth Lakes. The Minarets are one mile to the west and Devils Postpile National Monument is five miles to the southeast. Topographic relief is significant as the west aspect rises over above Iceberg Lake in approximately one-half mile.

History

The descriptive toponym was likely applied during an 1898–99 survey by the USGS, and has been officially adopted by the U.S. Board on Geographic Names.
The first ascent of the summit was recorded August 13, 1933, by Craig Barbash and Howard Gates.
The Minaret Mine was located on the south aspect of the ridge. Lead was mined there, but the remote location made mining unprofitable, and the mine ceased operations in the early 1930s.
Volcanic Ridge is the site of the fatal 2007 airplane crash of Steve Fossett.

Climate

According to the Köppen climate classification system, Volcanic Ridge is located in an alpine climate zone. 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. Precipitation runoff from this landform drains to the Middle Fork San Joaquin River.
