Details for: Nantaisan
Nantai stratovolcano on the right horizon rises above Yunoko lake and the Senjogahara plain (right center). Lava flows from the early stage of the construction of Nantai volcano dammed up the Daiyo River, forming Lake Chuzenji, out of view to the right. The dramatic Kegon waterfall plunges over this barrier. A collapse depression on the north (left) side of the volcano gives Nantai a somewhat asymmetrical profile. The latest effusive activity of Nantai produced the Osawa lava flow, which traveled from the breached crater down the north flank. Photo by Yukio Hayakawa (Gunma University).
