Gareloi in the western Aleutian Islands is seen here from the S. This photo shows lava flows with clear levees from a 1980s eruption. The 8 x 10 km diameter Gareloi Island consists of a stratovolcano with two peaks and a SE-trending fissure. A fissure formed during an eruption in 1929 and extends from the southern summit to the sea.
