Mount Douglas

Mount Douglas is a stratovolcano in southern Alaska, south of Kamishak Bay near the northeastern end of the Alaska Peninsula, within Katmai National Park and Preserve. Officially named in 1906 after nearby Cape Douglas, it is mapped simply as a mountain, but its volcanic character remains significant. Although its last eruption is unknown, it is believed to have erupted in the Holocene, indicating geologically recent activity. Its warm, highly acidic crater lake and relatively fresh, unglaciated lava flows on the north flank point to that recent volcanic history. These features make it an active volcanic landscape in one of Alaska’s most volcanically dynamic regions.
