Kamiyama, the highest of a group of lava domes forming the central cone complex of Hakoneyama caldera, rises E of Ashinoko (Lake Ashi). The lake was formed about 3,100 years ago when collapse of the NW side of Kamiyama dammed the Hayakawa river valley at the N end of the lake (lower left). Dome growth at Kamiyama about 2,900 years ago marks the most recent eruptive activity. Photo by Lee Siebert, 1977 (Smithsonian Institution).
