The Obsidian Dome and its neighbors Glass Creek and Deadman Dome all erupted in early fall of 1350. Scientists were able to date this last volcanic activity based on tree rings. In this eruption, magma flew into large amounts of groundwater which led to massive explosions that formed the nearby Inyo Craters.
