Pothole Dome
Pothole Dome is a granite dome on the west side of Tuolumne Meadows, in Yosemite National Park located at Tioga Road mile marker 18.[1] Near Pothole Dome is Marmot Dome.[3] The summit of the dome is easily accessible by foot from a parking area on the Tioga Road at mile marker 18. The view from the summit includes most of Tuolumne Meadows and in the distance, Cathedral Peak.[4] 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.[5]
