This unnamed, complex crater is approximately 30 kilometers in diameter. The transition from a simple bowl-shaped crater to a complex crater exhibiting central peaks or pits, flat floors and terraced walls takes place in craters that are larger than about 8 to 10 kilometers in diameter on Mars. Because the central uplifts of complex craters expose rocks and materials that originated deep below the surface, researchers can use these regions as possible “windows” to view the rocks beneath the surface.
A northeast-southwest linear valley or trough transects this region dividing the uplift in two. This valley, or lineation, may have resulted from processes occurring during the uplift event or subsequent to crater formation. When seen at HiRISE resolution the center of this valley seems to bisect what may be a small (less than a kilometer wide) central pit.
