Date Taken
1914
Summary
Yosemite National Park, California. Front of Half Dome. The cliff came into existence first by removal of thin rock sheets from a zone of nearly vertical joints, still visible in the shoulders at the northeast (left) end. The great monolith then began to exfoliate at its newly exposed surface, in plane shells curving under the old shells at the top. The old shells now form an overhanging cornice. Circa 1914. Plate 50-B, U.S. Geological Survey Professional paper 160.
