Details for: Great Sitkin
Great Sitkin in the Andreanof Islands is seen here from Finger Bay on Adak Island. The edifice was constructed within a caldera, part of which forms the high snow-covered peak to the right. The post-caldera cone contains a 0.8 x 1.2 km ice-filled summit crater. The rim forms the irregular summit on the left horizon. A lava dome 400-600 m wide was emplaced through a glacier in 1945.
