Snow and ice cover the Kaguyak caldera lake in this view from the NW. The caldera formed during a voluminous eruption about 5,800 years ago that produced pyroclastic flows that reached Shelikof Strait. Two lava domes, one large and the other seen just above the center of the lake, were built after the caldera-forming eruption.
