Kamuinupuri is a small cone on the SE rim of Mashu caldera. Growth of Kamuinupuri post-dated the roughly 7,000-year-old caldera collapse. The steep scarp below the summit is the NE wall of a 1.2 x 1.5 km caldera that formed at the summit about 1,000 years ago. Photo by Lee Siebert, 1977 (Smithsonian Institution).
