The "ice" you see on the crater rim is not ice, it's a type of rock very common on Mars (in the humble opinion of someone that has downloaded 1134

This is that crater (if I am not mistaken) viewed at 50% zoom with IAS viewer (if you are interested in HiRISE images I strongly suggest you donwload
it, it's the best way of seeing those huge images).
is a link to the 100% zoom image of that crater (that I don't know if its
really a crater).
Edit to add the same image as above but in its RGB version, with 50% zoom.
And a link to the 100% zoom image
I also thought it could be interesting to see the greyscale image because it shows a bigger area (the colour sensors only show the central part of the
This is an image from that area at 25% zoom to show why I don't think that is a crater.
