Kepler Crater "land slides" Download here : https://www.flickr.com/photos/terraform-mars/50610621241 [LROC] he walls of impact craters slowly retreat backwards, widening the crater, as the crater ages due to wall material moving downslope onto the floor. Movement can be a grain by grain creep wherein material slowly creeps down the wall over time, or it can occur as a catastrophic event in which a large amount of debris cascades down the slope. The walls of Kepler crater (30 kilometer diameter) exhibit numerous landslides. In this example, a landslide of dark material begins about 100 meters below the rim from a narrow box canyon. The box canyon is about 50 meters wide and 300 meters long. Overall, the slide is extends some 2300 meters (from the end of the canyon to its base). The base of the slide is on a fault block that lies some 1800 meters below the rim. The wall slope is about 33 degrees.
