This image shows a fresh, 2 kilometer diameter crater on the floor of the much larger Pasteur Crater.

The enhanced HiRISE color creates a stunning mixture of gold and blue, which here is superficially remniscent of the Great Blue Hole near Belize City.

Of course, this isn't water but sand that has collected. Has some of it blown in from the surrounding terrain?
