Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Moffett
Mount Moffett has several flank lava domes and is seen here across Andrew Bay to the SW from Mount Adagdak. Andrew Bay volcano is the oldest of three volcanic centers on northern Adak Island. Mount Moffett rises above Adak (out of view to the left), the largest town of the Aleutians. Photo courtesy of Alaska Volcano Observatory, U.S. Geological Survey.

Rising above Adak, the largest town of the Aleutians, Mount Moffett is a modest-sized, eroded stratovolcano with several flank lava domes. The summit cone has been largely destroyed by glacial erosion, and has been filled by an andesitic plug dome. Five other lava domes are scattered over the flanks of the volcano. The south flank lava dome is one of the youngest features of the northern Adak Island volcanoes. The Heart Lake lava flow west of Sweeper Cove on the SE side of the volcano is another young volcanic feature. Several Holocene ash layers on Adak Island have been attributed to Moffett volcano. Its proximity to Adak Naval Air Station makes this one of the most accessible of the Aleutian volcanoes. Kiguga Warm Springs are located at Cape Kiguga, west of Mount Moffet, and the northern part of Adak Island has been investigated for geothermal power production.
