Adagdak is located at the NE tip of Adak Island. Three stages of volcanism were mapped, the youngest of which was a lava dome dated at about 210,000 years. Andrew Bay Hot Springs lie along the coast west of Mount Adagdak, and the northern part of Adak Island has been investigated for geothermal power potential.
