Shikotsu caldera, seen from the SE with Yoteizan volcano on the horizon, is a 13 x 15 km caldera filled by Lake Shikotsu. Following formation of the caldera more than 30,000 years ago, three small cones were constructed along a NW-trend across the caldera. Snow-capped Tarumai (left center) formed near the SE rim of the caldera, along with Fuppushi to its right. A third volcano, Eniwa, was constructed on the NW caldera rim at the far side of the lake.
