In this image, we see the saddle between two valleys named Dingo Gap—in Gale Crater—where the rover Curiosity just traversed. The gap is spanned by a single dune visible both from the ground and from orbit. (The rover itself is not in this image as it was acquired before MSL landed.)

With images taken with the Mastcam on Curiosity, we can see a view looking northwest and the Dingo Gap where the rover recently crossed.
