Cathedral Peak is the crowning summit of the Cathedral Range, a mountain range in the south-central portion of Yosemite National Park in Tuolumne County, California. The range is an offshoot of the Sierra Nevada Mountains. 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

The west peak of Cathedral Peak (shown foreshortened in the photograph) is called Eichorn Pinnacle, after Jules Eichorn, who first ascended a YDS 5.4 route in 1931.

In 1869, John Muir wrote "My first summer in the Sierra", where he described Cathedral Peak as

Geology

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 83 million years ago. Its composition is mainly Cretaceous-era granodiorite with phenocrysts of microcline.
