Griggs is the highest of a group of volcanoes in the Katmai area, located 10 km behind the volcanic arc. Active fumaroles are within the summit crater and along the upper SW flank. Tephra from the 1912 Novarupta eruption cover the flanks in this 1990 view from the SW. Photo by Game McGimsey, 1990 (U.S. Geological Survey, Alaska Volcano Observatory).
