Pothole Dome is a granite dome on the West side of Tuolumne Meadows, in Yosemite National Park. The summit of the dome is easily accessible by foot from a parking area on the Tioga Road. The view from the summit includes most of Tuolumne Meadows and in the distance, Cathedral Peak. The dome gives evidence of many of the geologic processes at work in Yosemite during and after the last ice age. In particular, the stranded, rounded boulders from a glacier that has long since retreated, and the water-eroded "potholes" provide evidence of two ways that water can interact with granite.
