Kolana Rock is a prominent granite dome located along the southern edge of Hetch Hetchy Valley in Yosemite National Park. John Muir stated that Kolana was the Indian name for the rock. It towers 2000 ft above the Hetch Hetchy Reservoir, and is across from Hetch Hetchy Dome. The dome was closed to rock climbing for many years during the breeding season of the Peregrine Falcon. The closure was lifted in 2013.
