Mount Douglas is a large stratovolcano (a cone-shaped volcano built up by many layers of hardened lava and ash) located in Alaska. It stands south of Kamishak Bay, in the northeastern part of the Alaska Peninsula. This impressive mountain is found within the Katmai National Park and Preserve in Kenai Peninsula Borough, which is like a county in Alaska.

Mount Douglas: An Alaskan Volcano
Mount Douglas was officially named in 1906. It got its name from the nearby Cape Douglas. This naming was based on a report from 1904 by a geologist named G. C. Martin from the United States Geological Survey (USGS).
Where is Mount Douglas Located?
This volcano is part of the Aleutian Range, a long chain of mountains that stretches across the Alaska Peninsula. It's a remote area, known for its wild beauty and many volcanoes. The mountain's exact location is 58°51′36″N 153°31′59″W.
What Makes Mount Douglas Special?
Mount Douglas is known for its unique crater lake at the top. This lake is about 160 meters (525 feet) wide. In 1982, the lake's water was warm, around 21°C (70°F). It was also very acidic, with a pH of 1. To give you an idea, a pH of 1 is similar to battery acid or very strong lemon juice! Later, in 1991, even hotter temperatures of 114-118°C (237-244°F) were measured in the lake.
On the northern side of the volcano, you can find lava flows that haven't been touched by glaciers or worn away much by weather. This suggests they are relatively new.
When Did Mount Douglas Last Erupt?
Scientists are not exactly sure when Mount Douglas last erupted. However, they believe it happened during the Holocene epoch. The Holocene is the current geological time period, which began about 11,700 years ago. This means the last eruption was in relatively recent geological history.
