Hollow close-up

Hollow close-up
Hollow close-up An area within an unnamed basin has been etched by hollows. This is the only area within the basin in which hollows are found. To the bottom left is part of the peak ring of the basin. This peak ring has been modified by subsequent impacts. This is a high-resolution observation, at 21 meters per pixel, so the full image is about 27 kilometers square. NASA / JHUAPL / CIW
