The steep topography at the right is the eastern rim of a scarp created by the 1888 collapse of Koandaisan, one of a group of cones forming Bandaisan. The two lakes in the distance, Onogawa (left) and Akimoto (right), formed after the resulting debris avalanche blocked river drainages. The caldera walls expose stratigraphy of pyroclastic deposits overlain by lava flows.
