Description
From Smithsonian Institution, online database, accessed December 8, 2003: "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 cluster of four closely spaced and mostly ice-covered vents. Mount Denison lies at the SW end of this volcanic 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) [1] . The precise age of the most recent activity at Denison is not known, but the volcano was considered to have been active during the Holocene [2] ."Name Origin
Mount Denison's name was suggested by K.F. Mather, an alumnus of Denison University, Granville, Ohio. Brooks published the name in 1925 (Orth, 1971).
