Mount Mallory is a mountain located in the Sierra Nevada of California. The boundary between Inyo National Forest and Sequoia National Park runs across the summit. The peak was named in memory of George H. Leigh Mallory, of the 1924 British Mount Everest expedition, who was lost on Mount Everest, June, 1924. Norman Clyde advanced Mallory's and Andrew Irvine's names following their loss after attaining the highest altitude reached by a mountain climber.
