The mountain
兎森山 (Usumori-yama)
- Landform
- Usumori-yama is a volcanic hill on the edge of the Ou range, developed in 1990 and reaching 1,070 m. The lifts go to the top of it.
- Rock
- The top is andesite lava and pyroclastic rock from the early Pleistocene. Lower down it becomes Miocene marine sandstone, so the volcano is sitting on an old sea floor, and you cross the join on the way down.
