OK folks. I have to admit I'm starting to feel a little overwhelmed in HiRISE images already, and I know the tap hasn't even been turned fully on yet! There is just so much territory to be looked at.
To help us all see just a little bit more I propose that we start a 'Picture of the day' type thing (not necessarily one per day, the more the merrier ) of HiRISE screen sized sub-images. Not necessarily the most amazing bits, but a bit random, I find myself quite drawn to the less obvious bits that no one may have seen yet. I'm going to use the same filenames as the original images appended with approximate pixel coordinates of the sub-image so that it can be found easily in the original. James -------------------- |

No doubt the pits and pit-chains are something like terrestrial glacial caves and crevasses. Something that was once there is now gone. Coincidentally, the main JPL site is running a feature about some studies of moulins in Greenland glaciers.
I just wanted to clear up some potential confusion I may have caused with my earlier post. I was talking about some of the thickening and thinning of the layers seen in the HiRise image of the polar layered deposits, not the pits. Some of it looks flow induced to me. I tried earlier to find some physical property information about CO2 and H2O ice, but didn't find much that I could relate to shear or tensile strength. Surely it is out there somewhere. As for frozen brines, I don't know. -------------------- ...Tom
