Peulik volcano, a 1,474-m (4,836 ft)-high stratovolcano, as viewed from the Ukinrek Maars on the south shore of Becharof Lake on the Alaska Peninsula. In the middle distance is hummocky ground that probably represents debris-avalanche deposits from an older Peulik stratovolcano. Photograph by C. Neal, U.S. Geological Survey, June 25, 1993.
