Resumen geológico

Mount Dana is a small calc-alkaline volcano NE of Canoe Bay inlet at the head of Pavlof Bay consisting of an apron of volcaniclastic debris surrounding a central dome complex. The high point is located at the north rim of a 1.5 x 2 km crater, whose SW rim exposes Mesozoic sedimentary rocks. Andesitic lava domes occur on the west crater rim and as a small mound east of Knutson Lake inside the crater. Dana is the source of a mid-Holocene block-and-ash flow that reached the sea at Canoe Bay. No historical eruptions are known, but a 200-m-wide tufa mound and several cold springs are located on the SW flank.

Resumen de Wikipedia

Resumen en inglés

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.
