Mount Tulik, a small, older, deeply glaciated cone on the flank of Okmok.

Mt. Tulik, a flank vent on the southeastern flanks of Okmok volcano. This photo shows ash from the 2008 eruption coating the caldera rim and the eastern flanks of Mt Tulik.

The northeast portion of Umnak Island, as viewed from space. Okmok Caldera is visible in the center of the image. Just south of the caldera rim, Tulik volcano, a high cone on the flank of Okmok is visible; historical accounts often erroneously attribute eruptions to Tulik instead of Okmok. This photograph is mission ISS014, Roll E, Frame 16643 from Image Science and Analysis Laboratory, NASA-Johnson Space Center. "The Gateway to Astronaut Photography of Earth." and is available at http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS014&roll=E&frame=16643
