Landslides in an Impact Crater


This impact crater, approximately 25 km (16 miles) in diameter, has been heavily modified by landslides. Portions of the crater's walls detached and slumped towards the floor, producing terraces along the wall, landslide deposits on the crater floor, and modifying the crater's outline from circular to irregular. The small bright spots on the landslide deposits (near the top of the image) may be hollows, similar to those seen in other impact craters on Mercury.
