The summits of Pavlof Sister (left) and Pavlof (right) rise above a roughly 1,100-m-high saddle. They are viewed here in 1975 from lowlands to the NW. Pavlof is darkened by recent ash deposition and has been the source of frequent eruptions in historical time. Little Pavlof, a cone on the right flank of Pavlof, was also constructed along a line of vents trending NE from Emmons Lake caldera.
