Mount Denison

Mount Denison is a stratovolcano at the end of a volcanic chain on the Alaska Peninsula that rises to 2,317 meters (7,606 feet). The mountain has a prominence of 475 meters (1,558 feet) and sits in a remote section of the national park.

Harvard professor Kirtley Fletcher Mather identified the peak in 1923 and named it after Denison University, where he had studied. The name honored the academic institution with which Mather was connected.

The first successful climbers of Mount Denison in 1978 maintained strong connections to Denison University as students, alumni, or faculty members.

Reaching the summit requires glacier climbing techniques and experience with technical gear in challenging conditions. Visitors should prepare for extremely remote terrain and unpredictable weather.

Different surveying sources report varying elevations for the peak, which has led to ongoing debate about its status as the park's highest summit. Some measurements challenge its ranking compared to nearby Mount Griggs.
