Mt. Clark (11,522 feet / 3,511 meters)

Half Dome tends to dominate the views at Glacier Point, but when you look off to the southeast, Mts. Clark and Starr King are the stars of the skyline. Mt. Clark is nearly 3,000 feet higher than Half Dome and worth focusing your binoculars on (there's also a telescope just below the Geology Hut).
