Mount Griggs, Stratovolcano in Katmai National Park, Alaska, US
Mount Griggs rises 2,317 meters above sea level, featuring three concentric craters and a symmetrical cone shape within the Aleutian Range.
The volcano received its name from Dr. Robert Fiske Griggs, a botanist whose research led to establishing Katmai National Monument in 1918.
Scientists regularly study Mount Griggs to understand volcanic behavior and magma composition, which differs from other volcanoes in the Katmai group.
The mountain's slopes contain active fumaroles that produce loud roars audible from the valley floor, requiring visitors to maintain safe distances.
Despite having no recorded historic eruptions, the volcano maintains vigorous fumarolic activity in its summit crater and along the southwest flank.
