Panum Crater: Obsidian Dome and Volcanic Rim Hike
South of Mono Lake, Panum Crater is a young (600â700 years old) obsidian dome and explosion pit with a short rim trail. This accessible volcanic feature offers views of Mono Lake and the Mono Craters chain; a quick geological highlight.
A Young Dome and Obsidian Landscape
Panum Crater blends glassy obsidian flows, pumice, and a central explosion pit with panoramic Mono Lake vistas. Sparse sagebrush and lichens cover the dome; the site showcases recent volcanic activity in the Mono-Inyo chain.
Adventure With a Conservation Conscience
Panum Crater Trail (0.5-mile loop, easy-moderate) climbs the rim for views; explore obsidian flows carefully.
Access is open: free roadside parking, sunrise to sunset, pack out waste, stay on trail. No major closures; respect fragile volcanic surfaces.
Panum Crater delivers Eastern Sierra obsidian dome hiking with lake views. For geology lovers seeking young volcanic features, the short rim repays close inspection; a glassy Mono Basin gem.
