Mount Steller, Stratovolcano in Katmai National Park, Alaska.

Mount Steller is a stratovolcano on the Alaska Peninsula in Katmai National Park, reaching 2,272 meters at the end of a volcanic chain between Mount Denison and Mount Kukak. The peak and its surroundings lie under glaciers in a remote sector of the park.

Mount Steller was presumably named for Georg Wilhelm Steller, the German botanist, zoologist and physician who travelled with Vitus Bering's 1741 expedition through this region. The sources record no formal naming date or agency. The volcano is believed to have erupted during the Holocene, though the date of its last eruption is unknown.

The name honours Georg Wilhelm Steller, the German botanist, zoologist and physician who travelled with Vitus Bering's expedition along this coast in 1741. The volcano stands in the glacier-covered, very remote sector of Katmai National Park between Mount Denison and Mount Kukak.

The area is reachable only by boat or aircraft since no roads lead to this remote volcano and the nearest settlements are far away. The best time to visit is during the warmer months when weather conditions are more stable and water and air transport connections work more reliably.

The exact number and location of volcanic vents around Mount Steller remain unclear due to thick glaciers covering the mountain and its surroundings. Scientists cannot fully map these features, making this peak hold more geological mysteries than its appearance first suggests.
