Obsidian Dome: Volcanic Landscape and Glassy Flows
Near June Lake off Highway 395, Obsidian Dome is a striking rhyolitic lava flow with glossy black obsidian and pumice. This accessible volcanic site offers short trails across the dome and panoramic views; a quick stop for geology enthusiasts.
A Lava Flow and Obsidian Mosaic
Obsidian Dome features massive obsidian flows, pumice layers, and fractured volcanic rock with sparse sagebrush. The glassy surface reflects light; the dome showcases rapid lava cooling in the Mono-Inyo volcanic chain.
Adventure With a Conservation Conscience
Short loop trails (0.5 to 1 mile) explore flows; views of June Lake basin.
Access is open: roadside parking, sunrise to sunset, pack out waste, stay on paths. No major closures; caution on sharp obsidian.
Obsidian Dome delivers Mono County volcanic landscape hiking with glassy beauty. For those seeking obsidian flows and Sierra vistas, the short trails repay exploration; a shiny volcanic highlight.
