Mount Dutton, Volcanic summit in Aleutian Islands, US.

Mount Dutton is a 1,473 m stratovolcano in the Aleutian Range, on the Alaska Peninsula. Its summit is built of a series of lava domes, and the volcano is heavily glaciated. An avalanche swept andesitic lava flows and several domes from its flank westward and southward toward Belkofski Bay.

Mount Dutton is a glaciated stratovolcano on the Alaska Peninsula, close to King Cove. Its recent history includes a large avalanche that carried andesitic lava flows and several lava domes from its flank westward and southward toward Belkofski Bay. Earthquake swarms struck the volcano's vicinity between 1984 and 1985, and another swarm followed in the summer of 1988.

Fishing communities near the mountain have built their way of life around the sea. People here depend on the waters for work and tradition, making the ocean central to how they live.

Mount Dutton lies just short of 9 miles (14 km) from King Cove, a fishing headquarters for the locality. The summit is heavily glaciated, and the volcano has no road access; approach is by air or boat to the King Cove area, then overland or by water.

The mountain has numerous volcanic vents scattered across its slopes. Strong earthquake activity in the 1980s revealed that the volcano remains geologically active beneath its frozen surface.
