Mount Griggs volcano, 2,317-m (7,602 ft)-high, here seen from the west rim of Katmai caldera, lies 10 km (6 mi) behind the volcanic arc defined by other Katmai group volcanoes. Although no historic eruptions have been reported from Mount Griggs, vigorously active fumaroles persist in a summit crater and along the upper southwest flank. The slopes of Mount Griggs are heavily mantled by fallout from the 1912 eruption of Novarupta volcano. View is to the northwest. Photograph by Game McGimsey, U.S. Geological Survey, July 16, 1990.
