All that new Hirise imagery started me thinking about this topic again and I found this link. I was surprised to see the image with what may be three more arches, apparently crying out for some follow-up observation. If this was discussed before then I missed it. Anybody have any news on this?

If there are caves on Mars - which we now know there are, on the flanks of the giant Tharsis volcanoes - then IMO there are almost certainly also arches. I really hope HiRISE clinches an unmistakeable example of a Martian arch.
