Photo Gallery

Yantarni volcano, a small, 1345-m-high andesitic stratovoclano with no known historical activity, is located on the Alaska Peninsula. This view from the east shows the central lava dome forming the summit. The low knobs on both sides of the dome at the height of the long left-hand ridge are remnants of a large crater breached to the NE, which formed during collapse of the volcano about 2000-3500 years ago.
