Mount Agassiz, Mountain summit in Inyo County and Fresno County, United States.
Mount Agassiz is a mountain peak in California's Sierra Nevada that rises to approximately 13,900 feet. It sits near Bishop Pass and can be reached via established climbing routes from the surrounding valleys.
The peak was named Agassiz Needle in 1879 by Lilbourne Winchell to honor Louis Agassiz, a Harvard professor of zoology and geology. Norman Clyde made the first recorded ascent in 1925 using a challenging route through a canyon and along a ridge.
The peak marks the boundary between Kings Canyon National Park and Inyo National Forest. Hikers and climbers passing through the area use it as a natural reference point in this mountain landscape.
The Bishop Pass Trail from South Lake is the main approach to this peak for most climbers. The west slope provides the most direct route, though experience and proper equipment are needed for safe climbing.
The west slope is significantly easier to climb than other approaches, a fact many climbers overlook when planning their routes. This allows for a more efficient ascent compared to other sides of the mountain.
