Mount Douglas, Stratovolcano in Katmai National Park, Alaska, US.
Mount Douglas is a stratovolcano located in Katmai National Park on the Alaska Peninsula. A warm crater lake sits within the summit caldera, surrounded by steep volcanic slopes and exposed lava formations.
The volcano was formally named in 1906 following geological surveys of the region. The name derived from the nearby Cape Douglas geographic feature.
The Alaska Volcano Observatory monitors Mount Douglas as part of its network of volcanic formations across the Aleutian Arc region.
Access to the volcano is limited and typically requires air travel from a remote location. Visitors should prepare for harsh weather conditions and challenging terrain on the approach.
The crater lake contains exceptionally acidic water, making it a rare example of a highly corrosive volcanic system. This extreme chemistry draws scientific interest from researchers studying volcanic hydrothermal processes.
