Mount Hitchcock (center). Sequoia National Park, California. No Date.
Summary
Sequoia National Park, California. Mount Hitchcock (center), viewed from the Whitney Trail across upper Whitney Canyon and Hitchcock Lake (foreground). Zones of fracturing in the floor of the canyon have controlled the erosive action of the glacier. Lakes and snowdrifts mark the depressions quarried out in these zones. The intermediate humps, composed of sparsely fractured rock, have been subject chiefly to the slower process of grinding. Except for the accumulation of rock debris at the base of Mount Hitchcock, this part of the canyon has undergone only insignificant changes since the disappearance of the glacier. Photo by K.
