Background:

The geology and timing of volcanism on this small uninhabited 3 x 4 km island, located in the Andreanof islands 50 km west of Adak and 15 km west of Kanaga volcano, are unknown (Coats, 1956). Apparent deposits of a massive submarine debris-avalanche deposit extend offshore to the NE. Smith et al. (1978) considered Bobrof to be of possible Holocene age. Andesitic pyroclastic-flow deposits are present on the 738-m-high volcano.
