Summary
Sequoia National Park, California. Alta Peak (11,211 feet). The summit is composed of frost-shattered remnants of exfoliation shells. Formerly the shells extended toward the left in a descending curve outlining a dome, but the excavation of a cirque by a small glacier has pared away the north side of the dome, thereby giving the summit the unsymmetrical profile. The upper part of the cirque wall, which is several hundred feet high, is visible in the lower left corner. Photo by J.C. Patten, 1935. Figure 30, U.S. Geological Survey Professional paper 504-A.
