This HiRISE image (PSP_001840_2000) samples the plains between the large shelf volcanoes in the Tharsis region of Mars.

The long scarps in the area have been formed by faults as the ground was pulled apart. The large circular depression on the edge of the image is a giant collapse pit that appears to be related to the opening up of crust.

If you look at this image carefully, much of the plains appears blurry, as if the picture was out of focus. But HiRISE remains in perfect focus and it is Mars that is actually this blurry. Soft wind-blown dust mutes all the features in the area to create this effect.
