Three volcanoes are constructed along an E-W line on the eastern half of Unimak Island. Roundtop in the foreground is glacially eroded and has Holocene pyroclastic flow deposits and a group of lava domes to the south. Isanotski (background) and Shishaldin (midground) are the prominent peaks behind Roundtop. Photo by Clayton and Marcia Brown, 1986 (courtesy of John Reeder, Alaska Div. Geology Geophysical Surveys).
