The small 3 x 4 km volcanic island of Bobrof lies 50 km west of Adak and 15 km west of Kanaga volcano. The irregular shoreline of the island has a half dozen small cliff-bound peninsulas. A deep valley (center) extends from the summit to the northern coast of the uninhabited island. The geology and timing of volcanism on Bobrof are unknown. Andesitic pyroclastic-flow deposits are present on the 738-m-high volcano.
