The western side of Taunshits contains a large horseshoe-shaped crater that formed about 8,000 years ago during an eruption that produced a debris avalanche and directed blast similar to that at Mount St. Helens in 1980. A viscous lava flow (center) erupted after the collapse from a vent at the top of the collapse scarp.
