Check out the terrain in this mosaic

MSL Sol 4873 MastCam Mosaic.

This vista shows the wind sculpted rocks on the workspace.

We can also see a small patch of rock that has been cleaned with the rover's dust removal tool (see the lower LH rock slab)

The DRT is a rotating stainless steel brush.

For scale: The patch of the rock from which dust has been brushed away is about 1.85 inches by 2.44 inches (47 millimeters by 62 millimeters)
