Hues in a Crater Slope

Hues in a Crater Slope 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. via NASA http://ift.tt/2iDXvCA
