Description

From Wood and Kienle (1990) [1] : "Mount Dana is a small calc-alkaline volcanic center consisting largely of volcaniclastic debris surrounding a central dome or domes, reminiscent of Augustine volcano. The volcano rests on relatively undeformed Jurassic and Cretaceous marine sandstone and shale. Mesozoic sedimentary rocks, dipping steeply southwest, form the southwest crater rim and are exposed in the canyon at the crater outlet. Remnants of a high-silica andesite dome are exposed on the west crater rim and in a small mound on the east side of Knutson Lake. A block-and-ash flow erupted 3,840 yBP fills valleys south and west of the crater. A 200-m-wide tufa mound and several cold springs occur at elevations of 490 to 520 m on the southwest flank."

Name Origin

"Mount Dana" is a local name for this volcano, reported by the U.S. Geological Survey in 1929 (Orth, 1971).
