Cima Volcanic Field, California. Lava flows and cinder cones, usually scattered over a few hundred square kilometres, litter basaltic lava fields. Across southern Nevada and California are several such fields, one of which is the Lunar Crater Field in central Nevada. The photograph shows two cinder cones in another basalt field, the Cima Basaltic Lava Field in southern California. The cinder cones and lava flows range between 7.55 Ma and 0.015 Ma (Turrin, et al., 1985).
