The name is translated from Russian "Ostrova Chetyre Soposhnye," meaning "Islands of Four Volcanoes" (Sarichev, 1826, map 3) and was applied by the early Russian explorers because of four prominent volcanoes located on four of the islands. The Aleut name "Unigun" was reported in 1940 by Father Veniaminov. There appears to be confusion regarding the names of these islands, possibly because only four of the five are on most early maps and charts. The present names were gathered in 1894 by a field party on the USS Concord and published in 1895 by the U.S. Navy Hydrography Office (Chart 8).^[2] Volcano 1. ...
