Mount Churchill, Stratovolcano in Wrangell-St. Elias National Park, Alaska, US
Mount Churchill is a stratovolcano in Wrangell-St. Elias National Park in Alaska that rises to approximately 4,766 meters (15,620 feet) in elevation. The volcano features a broad caldera on its eastern side and is heavily covered by glaciers and snow-covered slopes that dominate its appearance.
The mountain developed through volcanic activity and experienced two major eruptions that ejected white volcanic ash across vast distances. The most recent of these significant eruptions occurred around winter 852/853 and distributed ash across Alaska and western Canada.
Scientists extracted the longest non-polar ice core near Mount Churchill, spanning 460.96 meters, which provides data about historical climate patterns.
