This area seen by NASA's Mars Reconnaissance Orbiter is known as the Deuteronilus contact of the Isidis Basin; it has been interpreted as a possible ancient shoreline. There are also suggestions that this contact is of volcanic origin.

This image from NASA's Mars Odyssey spacecraft shows the southwestern floor of Gale Crater. A fairly large channel that dissects the crater rim is visible entering from the bottom of the frame and continuing northward.

In the winter a layer of carbon dioxide ice (dry ice) covers the north polar sand dunes as shown by NASA's Mars Reconnaissance Orbiter. In the spring the sublimation of the ice (going directly from ice to gas) causes a host of uniquely Martian phenomena.
