Mount Ansel Adams is a prominent Sierra Nevada peak in Yosemite National Park near the park’s eastern boundary, rising 11,766 feet at the head of the Lyell Fork of the Merced River. Named in 1985 for landscape photographer and conservationist Ansel Adams, it reflects his close association with both the Sierra Nevada and Yosemite. The mountain also honors his broader public role in American conservation, including 37 years on the Sierra Club’s board of directors, connecting the peak to both his celebrated photography and his long commitment to protecting natural landscapes.
