This new HIRISE shows slope streaks in Marte Valles, extending down a sloping ridge to an escarpment. The photo shows an attractive view, but what jumps out at me is when you scroll down to the southwest corner of the photo.

The prevailing lighting is from the southwest, casting shadows on the northeast side of the ridge. But on the southwest side of the escarpment is an area of deep shade, where there should be a sunlit escarpment. It appears that the escarpment has been undercut by a cave. And in this case, it is not a vertical cave, or sinkhole, but instead seems to be one that a rover (MSL?) could roll right into.

Ok, technically, no abyss. But I wanted to get USTRAX's attention!

That image displays an amazing collection of slope streaks of various ages. Interestingly, the new abyss very much resembles El Dorado (aka, the original Abyss). Here is a full res crop of that area from IAS Viewer.
