Herbert Island

Yunaska Island is 16 miles (26 km) west southwest of Herbert Island.

Measuring 6.2 miles (10.0 km) across, Herbert Island is somewhat circular in shape and is covered by the 4,200-foot (1,300 m) Herbert Volcano, whose 2-kilometre (1.2 mi) wide caldera is one of the largest in the Aleutian Islands.

The Herbert Volcano is most likely a stratovolcano.
