About this image

This impact crater is located in Elysium Planitia and contains a well-preserved central peak in the center of the crater, in contrast with the slumped crater walls. Impact craters are divided into two groups based on morphology: simple craters and complex craters. Based on the morphologic characteristics of this crater, a central peak as well as a shallow crater depth verses crater diameter, this impact crater is defined as a complex crater. The central peak is formed as the initial deep crater floor rebounds from the compressional shock of the impact. A good diagram showing the structural difference between simple and complex craters is http://www.lpi.usra.edu/expmoon/science/craterstructure.html.
