Mount Steller

Steller

成層火山 · United States · 2279m

The rounded peak of Mount Steller is visible on the horizon at right-center beyond the slopes of Denison; the summit ridge of Snowy volcano forms the far-left skyline in this long-distance NE-looking view. The slopes of Mount Denison are seen on the right half of the photo, between the pointed summit in the center and the flatter peak to the far right, between which a glacier descends towards the middle of the image.

地質学的概要

Mount Steller is part of a chain of closely spaced volcanic peaks oriented NE-SW in Katmai National Park and lies between Mount Denision and Kukak volcanoes. Uncertainty surrounds the number and location of vents in this heavily glaciated area. The precise age of the most recent activity at Steller is not known, but the volcano was considered to have been active during the Holocene by Nye et al. (1998).
