This volcano is a member of the Stepovak Bay group. From Wood and Kienle (1990) [1] : "The Stepovak Bay group is a chain of five volcanoes at the southwest end of a N40 degrees E oriented linear segment of the Aleutian arc on the Alaska Peninsula. This same segment includes the better known Veniaminof and Aniakchak calderas. Three of the Stepovak Bay volcanoes [2, 4, and Kupreanof] have clearly had Holocene eruptions, resulting in three small debris flows filling late Pleistocene glacial valleys, and a small cinder cone and associated lava flow. The other two volcanoes (1 and 3) do not show unmistakable evidence of Holocene activity. They have ice-filled summit craters 500 m (1) and 300 m (3) in diameter that may be late Pleistocene age. These volcanoes have contributed to extensive late Tertiary and Quaternary lava flows, some extending near sea level."

Name Origin

"Stepovak Bay 2" is an informal name, after the nearby Stepovak Bay. As there are four unnamed volcanoes in this vicinity, they have been given numbers 1-4.
