HISTORYMount Katmai has long been recognized for its caldera collapse during the great pyroclastic eruption of 1912, but little has been reported about the geology of the ice-clad stratovolcano itself. In contrast to the andesite-dacite stratovolcanoes nearby, products of Mt. Katmai range from basalt to rhyolite. Before collapse in 1912, there were two overlapping cones with separate vent complexes and craters.
