SLIP-SLIDING AWAY. The impact of a meteorite near the edge of Noctis Labyrinthus appears to have set off an enormous landslide into the canyon. The crater (left center) is about 6.5 kilometers (4 miles) wide, and the landslide stretches for about 25 km (16 mi). Compare this slide's extent with the much smaller slides that lie at the foot of many sections of the canyon wall. This view looks west from an altitude of about 20 kilometers (12 miles), and there is no vertical exaggeration. (A 9 MB version of the image is available.)
