Carnegie Peak is a cinder cone ca. 38 thousand years old (Gutmann et al, 2000) of which the NE wall collapsed during eruptions to produce a debris flow extending toward the left foreground. A young basalt flow from the base of Carnegie Peak is further to the left. The Gran Desierto de Altar and the Gulf of California are in the background, and the trachyte that forms the base of Pinacate Peak is visible in the upper right.
