The extensively eroded edifice in this center of this Space Shuttle image with north to the upper right is Schmidt volcano. This large glacially eroded shield-like volcano is of mid- to upper-Pleistocene age. Following the Pleistocene cessation of activity at Schmidt volcano, regional basaltic volcanism produced some Holocene monogenetic cinder cones that were erupted through the eastern and NE flanks of the volcano. Schmidt is flanked by the conical Kronotsky stratovolcano at the lower left and the Gamchen complex at the far right. NASA Space Shuttle image ISS004-E-13788, 2002 (http://eol.jsc.nasa.gov/).
