It looks like collapse feature of some kind. Perhaps the cryokarst version of a doline?

You mean this patch of 'snow'?

Thanks for the image, I'm another one who hasn't invested in a computer that will handle the JPEG2000 images and wouldn't be able to see anything in full detail if you and others weren't kind enough to send selected crops.

When I looked at the center of the white area in Photoshop, I found that it was totally saturated -- every pixel was totally white. Was there any detail visible using the wider dynamic range of the JPEG2000?

Thanks again, Steve

Any computer can handle JPEG 2000 images, the trick is to find a program that will allow it with any computer... Once we have HiView it'll be even better, so...

I don't own a computer. I use our college system, which I share with several hundred staff and several thousand students. I am therefore not at liberty to download software when I choose. Nor can I download very large images or movies, though the systems people will do it for me if I make a special request as they have done for some MER panoramas, Mars and Titan movies and the Hayden Planetarium's excellent Orion Nebula in 3D movie. Websites that take more than a few seconds to open come up with 'access denied' and this includes NASA most of the time. I don't want to push my luck by asking for access to all the HiRISE images just now, so thank you once again Nix and the others who have posted cropped details (including the HiRISE team themselves for posting that detail of the natural arch). I just hope the system under development will work like the earlier 'zoomify' which was perfect for me.

About that patch of 'snow' - I wonder if there's enough to make a snowman? (Lightcolouredsubstrateman?)

At first glance, the light-toned material appears to be a substrate underlying the region, exposed by whatever process(es) formed that particular depression.


A depression?
It looks like an elevation to me... blink.gif

Nice perspective - just needs a tiny snowman waving to camera wink.gif - but it still looks like the white stuff is in a hollow (unless I'm seeing the whole thing backwards and those 'boulders' are actually small pits . . . )

Nice attempt, but the colorization has the curious effect of making the boulders so much harder to see than in the monochrome verison...

I'm reminded of images of pit craters on Ganymede. Though my default assumption is frost, I can't help but wonder about Alex's suggestion of a substrate. Could there be a process that would leech volatiles from a shallow substrate? Maybe acting as a cold sink and encouraging frost deposition?

No no, since it seems to be overexposed, it could be another bottomless (ice) hole like then Ultreya which was in contrast too dark for a final definition - so to speak it's (snow) white-little-Ultreya... biggrin.gif
