It gives me the impression that the general darkness is substantially real, or, not real, dependent upon whether the area has been a simple image as issued, or, rather, a doctored image of more than one item in overlay and assemblage.
I have selected a particular area for a 3X enlargement, and the obvious 3D correlation is rare and not common for an Earth scene. It does happen at times, however.
Can this be a former solid are decayed and altered, with remaining lighter items as parts of a 3D whole structure? Is the darker margins which cross the solids and mold to the shapes and area margins as particulates a residual material from the vast period of time Mars has presented this for our immediate viewing?
Was this a single mix now darker? Is this a valid image? Can a 3D appearance of overlay be a true 3D volume correlation of former solids?
I like the challenge. I believe this is real.
Is this a chemistry active spot of intrigue?
Could water be responsible for any of the current scene or chemistry alterations over time?
As the darker materials are not related to apparent motion or movement of the wheel, am I wrong about the cause of the darker margins and recesses, or is this a scene of 3D correlation with a wheel disturbance associated/
Curious about Curiosity.
Water anywhere? Water or moisture would shrink the size, thickness, or volume, wouldn't it?
It does give the general impression of something. I imagine a former oil diffusion of appearances, but for the 3D correlation of parts.
Is this image real at all?
I am sticking with chemistry and decay/erosion for now.
