Mount Saint Elias
Sharp became a published expert on the glacial geomorphology of the Sierra Nevada range, the Trinity Alps of northwestern California, the Olympic Peninsula of Washington, and Mount Saint Elias in the Fairweather Range of Alaska. In the winter season, he focused his geological field work in the Mojave Desert of California, with emphasis on the geomorphology of Cima Dome, and the sliding stones on the Racetrack Playa in northern Death Valley.
