Another image from Opportunity showing some of the heavily-textured rocks ringing Concepción crater in fascinating detail, color-calibrated by Stuart Atkinson for an approximation of Martian natural lighting. You can clearly see here the layered structure of the rocks, their angular shapes, the interesting “crust” that coats their sides as well as the small stone “berries” that cover their surfaces and hang from the edges.
I’m not sure how big these rocks are, but I’d wager a guess that the ones framed above are about 12″ across.
