Details for: Moffett

The slopes of Mount Adagdak provide a dramatic view of Mount Moffett across Andrew Bay to the SW. A narrow spit separates the bay from Andrew Lagoon (left). 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, and is a modest-sized, eroded stratovolcano with several flank lava domes. A south-flank lava dome is one of the youngest volcanic features of the northern Adak Island volcanoes. Photo courtesy of Alaska Volcano Observatory, U.S. Geological Survey.
