Geology and Minerals
Mount Dana is a small stratovolcano of the Alaska Peninsula, United States, located northeast of Canoe Bay inlet at the head of Pavlof Bay. It was the source of a major eruption about 3,840 years ago that produced a pyroclastic flow, which filled valleys south and west of the volcano's crater and reached the sea at Canoe Bay.
