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). The precise age of the most recent activity at Denison is not known.

The Global Volcanism Program is not aware of any Holocene eruptions from Denison. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Denison page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Denison.

Mount Denison lies in a poorly known section of Katmai National Park that contains one or more mostly ice-covered vents. The slopes of ice-mantled Mount Denison are seen on the right half of the photo, between the sharp-topped peak on the right-center horizon and the flatter peak at the extreme right. The rounded peak on the horizon beyond the slopes of Denison is Mount Steller volcano, and the summit ridge of Snowy volcano forms the far left skyline in this NE-looking view of the crest of the Alaska Peninsula range.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
