Impact craters expose the subsurface materials on the steep slopes of Mars. However, these slopes often experience rockfalls and debris avalanches that keep the surface clean of dust, revealing a variety of hues, like in this enhanced-color image from NASA's Mars Reconnaissance Orbiter, representing different rock types. The bright reddish material at the top of the crater rim is from a coating of the Martian dust.
