Dana volcan

Introduction:

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.

Even in the Danakil, one can find water deep under the sand. We are grateful for this opportunity to take showers. (Photo: Tom Pfeiffer)	0 m a.s.l. Although not yet at its bottom, we are already in the Danakil desert, here in a part where wind has accumulated sand. (Photo: Tom Pfeiffer)	Only 100 m above sea level.
