Gullies in the rim of a volcanic vent, Copland crater, Mercury
This image shows the wall of a volcanic vent located between the Rachmaninoff basin and Copland crater. The steep wall of the vent reveals high-reflectance layers and outcrops in which hollows are forming. The wall also has beautiful fluting in the form of gullies sculpted by landslides. The edges of the image are about 6.7 by 10.4 kilometers.
