During summer the flanks Mount Fuji have oxidized scoria and lava flows visible above the timberline. The two “shoulders” on the lower flanks, in this view from the north near Lake Yamanaka, are remnants of a group of older volcanoes over which the modern symmetrical volcano was constructed. The shoulder to the left is a remnant of Kofuji (Old Fuji) volcano, and the broader shoulder to the right is a segment of Komitake, a mid-Pleistocene volcano.
