A group of four late-Pleistocene to Holocene volcanoes is located along a NE-trending line SW of Kupreanof volcano. Stepovak Bay 3 cinder cone, located 3.5 km to the NE of Stepovak 2 cone, has a thick Holocene lava flow that originated from an indistinct, ice-filled 300-m-wide crater and entered the same valley as the lava flow from Stepovak Bay 2 (Wilson, 1989). Elsewhere (in Wood and Kienle, 1990), Wilson noted uncertainty about Holocene activity from Stepovak Bay 3.
