But some gullies are on steep slopes in equatorial regions, as seen in this image. This enhanced-color close-up image shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator on the Red Planet. The colors of the gully deposits match the colors of the eroded source materials. Krupac is a relatively young impact crater, but exposes ancient bedrock. Credit: NASA/JPL-Caltech/Univ. of Arizona
