description Pothole Dome (Yosemite) Overview
Pothole Dome is a granite dome located at the western edge of Tuolumne Meadows in Yosemite National Park, California. It is a classic example of a roche moutonnée, a geological formation shaped by glacial movement during the last ice age. The rock is distinguished by its smooth surface and the presence of deep glacially carved potholes that frequently trap meltwater. Because of its relatively low elevation and easy walk-up access, it is a popular destination for casual hikers seeking panoramic views of the surrounding meadow and Sierra Nevada peaks.
