Surface texture change or camera anomaly?

  • IsabelKershaw by IsabelKershaw

    Has anyone seen an image like this one? The surface texture looks very different between left and right sides of image.

    Here's one I made earlier - looks like another part of the same feature only darker, any scientists out there got any info on the proximity of the 2 images - timewise and spatially? ( http://planetfour.org/subjects/standard/50e73b7b5e2ed211dc0004c6.jpg )

    How do I copy and insert an image?

    They lool like they are interacting to me, overlapping....I think they are part of the same landscape......stand by for detonation.......

    I think that the surface is the same all the way across on both images, just that there is some thing on top of it in half the image (A super ginormous fan maybe)

    I think the two sides definitely do have different texture.
    On the right, the "grain" has random orientations and is generally more lumpy, (with the presence of some small bright boulders with dark edges).
    On the left, the grain is more linear. First thought about this linearity is that it could be the result of CO2 trying to escape in one direction, perhaps if there is a change of level/elevation towards a higher plateau. If that's the case, the edge between the two gives the impression of some sort of edge process - a naturally "feathered" look.
    On the other hand, is it just that the area to the left has deposits which have been given this linear texture by the prevailing wind, and these deposits are missing for some reason on the right....exposed plateau to right?
    I'm assuming there is ice under the dust on left side, but is the right necessarily covered by ice? Then again, those tiny boulders look as though they are darkened "downwind" - (possible mini fans?) - so that would suggest escape of gas around a boulder which has weakened the ice around it......Ah, but the ice could still have gone leaving the traces of mini-fan deposits around them?....
    Ooh...errr.....how many hypotheses have I mangled into this one?

    There is another thread started by SEJones here; http://talk.planetfour.org/#/boards/BPF0000001/discussions/DPF00009c8 using another pic with some subtlety's of lighting etc., but it's either the same area, or very nearly the same.
