Tresidder Peak is a mountain in Yosemite National Park in California near Cathedral Lakes. It has two summits, or arêtes, about half a mile apart, with the southern summit as the high point. That south peak's elevation has not been fixed precisely but is generally placed between 10,605 and 10,645 feet, while the northern summit appears on maps as Peak 10,450 and reaches 10,450 feet. Tresidder Peak is also the line parent of Clouds Rest. The mountain was named for Donald Tresidder, a former Stanford University president with a long association with Yosemite National Park.
