This photo shows the saddle between Nipesotsudake and Maruyama lava dome. The Nipesotsu-Maruyama volcano group, located E of Tokachidake, is composed of a number of overlapping lava domes constructed along a NW-SE trend. A minor phreatic eruption took place at Maruyama lava dome in 1898, and fumaroles are present on one of its summit craters.
