Pavlof Sister (center) and Pavlof (upper left) are twin stratovolcanoes whose summits are only 5 km apart. A low saddle about 1100-m high separates the conical volcanoes. They are the most prominent features along a NE-SW-trending line of vents that extends from Emmons Lake caldera, which is behind 2519-m Pavlof volcano in this view from the NE, to 2142-m Pavlof Sister volcano.
