Geological summary
Mount Denison lies near the head of the Serpent Tongue, Hook, and Hallo glaciers NE of Snowy volcano. This poorly known section of Katmai National Park contains a line of four closely spaced and mostly ice-covered volcanic peaks. Denison lies at the SW end of this chain, which also includes Steller, Kukak, and Devils Desk volcanoes. Orientation of lava flows and a thick cross-bedded tephra deposit suggest that a vent is located near Mount Denison (Swanson, in Wood and Kienle 1990). The precise age of the most recent activity at Denison is not known.
From Wikipedia
Mount Denison is a stratovolcano and one of the highest peaks on the Alaska Peninsula. Discovered in 1923 by Harvard professor Kirtley Fletcher Mather, the mountain was named for the geologist's alma mater, Denison University. The mountain's connection to Denison also include its first climbers: all members of the first two ascent teams as well as the group that attempted in 1977 were either students, alumni, or faculty of the university.
