Well the info lists PSP_003317_1975 as an anaglyph product for the image this enhanced clip has been taken from so one of the wizards here might be able to reprocess both similarly and then produce an anaglyph, the convergence angle looks pretty high to me but I'll let others comment on whether that makes this unusable or not.

This is the link to the full anaglyph image.
Even without the enhancement it should be not a problem to calculate the depth of the bright sunlit segment. -------------------- If Occam had heard my theory, things would be very different now.

Its very easy to imagine the bottom of that hole continuing as a lava tube under what seems to be an overhang at the right of that image, and possibly all the way through to the left hand side. May be an illusion of perspective and lighting though.

"Weird looking terrain in the latest PDS release."
it's odd but then this is Libya http://spaceflight.nasa.gov/gallery/images...s018e014770.jpg http://www.spaceref.com/news/viewsr.html?pid=30394 |

No, the landforms in ESP_020058_1865 are thought to be lithifed aeolian dunes that have been partially eroded. This is seen in multiple places around Arabia Terra. That HiRISE image was actually a case where we here on the CTX science ops team saw that terrain in a CTX image and then specifically asked HiRISE to shoot it for a higher-resolution look. Attached is a subframe of CTX P17_007571_1859_XI_05N335W, which covers the area of that HiRISE image (it's a little murky, as Arabia Terra is often cloudy). No one really knows what the heck is going on in the stuff in western Hellas (referred to informally as "taffy pull terrain"). ~Tanya -------------------- Twitter: @tanyaofmars

For convinience here is the abstract from LPSC. It makes for interesting reading, but I suggest great caution in declaring liquid water found, much less a habitable environment. Hopefully CRISM observations will make a stronger case or put this to bed.

In the literature, McEwan has been a critic of wet formation mechanisms. I don't think you need worry that he'll overreach.
