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 1354-m 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. Mount Dana is the source of a mid-Holocene block-and-ash flow that reached the sea at Canoe Bay. No historical eruptions are known from Dana, but a 200-m-wide tufa mound and several cold springs are located on the SW flank of the volcano.

Snow-covered Knutson Lake (lower left) lies within a 1.5 x 2 km wide crater of Mount Dana. The 1354-m-high Dana is a small calc-alkaline volcano consisting of a central dome complex surrounded by an apron of volcaniclastic debris. Andesitic lava domes occur on the west crater rim and as a small mound east of Knutson Lake inside the crater. A major eruption from Mount Dana about 3840 radiocarbon years ago produced a block-and-ash flow that filled valleys south and west of the crater.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
