Cathedral Peak is part of the Cathedral Range, a mountain range in the south-central portion of Yosemite National Park in eastern Mariposa and Tuolumne Counties. The range is an offshoot of the Sierra Nevada. The peak which lends its name to the range derives its name from its cathedral-shaped peak, which was formed by glacial activity: the peak remained uneroded above the glaciers in the Pleistocene.

Geography[edit]

Cathedral Peak has a subsidiary summit to the west called Eichorn Pinnacle, for Jules Eichorn, who first ascended a class 5.4 route to its summit on July 24, 1931 with Glen Dawson.

In 1869, John Muir wrote in My first summer in the Sierra:

Cathedral Peak, with Eichorn Pinnacle in the foreground.

Geology[edit]

The Cathedral Peak Granodiorite of Cathedral Peak is an intrusion into an area of older intrusive (or plutonic) and metamorphic rock in the Sierra Nevada Batholith. It is part of a grouping of intrusions called the Tuolumne Intrusive Suite. Cathedral Peak is the youngest of the rock formations in the Suite, dating to Cretaceous Period at 83 million years ago. Its composition is mainly granodiorite with phenocrysts of microcline.[6]
