Photo Gallery


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.
