From Smithsonian Institution, online database, accessed December 8, 2003: "Located at the end of a chain of volcanoes trending NE from Emmons Lake caldera, the symmetrical Pavlof Sister stratovolcano is somewhat more eroded than its twin volcano to the SW, Pavlof. The 2142-m-high Pavlof Sister is almost 400 m lower than Pavlof and has a sharper-peaked summit. Only one historical eruption, in the 18th century, was recorded from Pavlof Sister. The two symmetrical volcanoes form a dramatic backdrop to Pavlof Bay and Volcano Bay near the western end of the Alaska Peninsula."

Name Origin

The U.S. Geological Survey named Pavlof Sister in 1929 (Orth, 1971).
