This overlay shows a little more detail than Keyhole/Mars of the Aureum Chaos area, an example of the chaotic terrain contained in this part of the super-huge Valles Marineris.

Photo is from ESA, European Space Agency, where a wealth of Mars photos can be found (and there are a lot of "chaos" areas in the Mars "terrain" layer!)

The bright color and light & shadows really add a lot I think.. it makes me wonder what Jeff Goldblum's character in Jurassic Park would have to say.
