BackgroundDevils Desk, which rises 450 m above the top of Hook Glacier to its west, is the eroded neck of a former stratovolcano, most of which has been removed by extensive erosion. Three radial dikes exposed as ridges extend from the volcano toward the east. Devils Desk lies at the NE end of a glacier-mantled range containing small closely spaced volcanic centers that extends from Snowy Mountain, NE of Mount Katmai. The age of Devils Desk volcano is not known precisely. Although it was included in a list of probable Holocene volcanoes (Smith et al., 1978), extensive glacial dissection suggests it could be of Pleistocene age (Motyka et al., 1993), and Hildreth et al. (2003) obtained a Potassium-Argon date of about 245,000 years from a block on the SW face, similar to the age of one of the nearby rear-arc Savonoski cones.
