Other significant glacial features include Tehipite Dome, the largest granite dome in the Sierra, rising above the floor of Tehipite Valley. In Kings Canyon and across the high country, such sheer granite cliffs are subject to exfoliation, frost weathering and earthquakes which cause sudden and dramatic rockfalls. Over thousands of years, cliff collapses have built up large talus piles or scree slopes at their bases along almost every glacial valley in the park.
