Complex Crater

The crater in today's image is larger and more complex than the craters in yesterday's image. In large craters, the simple bowl shape is modified during crater formation. Flat floors, central peaks, and in this case, central pits are formed by rebound and heating of the impacted surface. Crater rims collapse due to gravity forming step-like slump blocks on the interior side of the rim. This crater also appears to be shedding material from the rims onto the crater floor in the form of fans and landslides. Finally, the presence of dunes in the lower left part of the crater indicates that wind activity has played a part in modifying this crater interior.
