Pavlof Sister is a symmetrical stratovolcano that forms a twin volcano with Pavlof volcano, whose lower flank forms the slope at the lower right in this view from the SW. Despite its youthful profile, Pavlof Sister has had only one historical eruption, which began in 1762. Glacial dissection has produced a series of parasol-ribbed ridges that radiate from the 2142-m, sharp-peaked summit.
