Roter Kamm impact crater

Roter Kamm impact crater

. Located in the Namib Desert, the raised rim of this impact crater makes a stark contrast with the darker background vegetation. Broad, shifting sand dunes, deposited by the wind, cover the crater floor, but rocks melted by the impact have been found on the crater rim. The rim diameter of this crater is 2,500 meters and its age is 3.7 0.3 million years. (Courtesy of Christian Koeberl and the Lunar and Planetary Institute.)
