QUOTE (elakdawalla @ May 23 2007, 03:41 PM)  ... It doesn't look to me like that one's on the Cushing et al list (see my blog entry for that list and image). Or is it? I don't see it in the seven that they show. I think antipode is correct, suggesting, "Who know how many of these things might turn up, and who knows how big they might be?" I took a hint from your discovery and started panning over that region with HRSCview, and I thought I saw several very small skylights that were not very convincing. I also came across the one you posted an image of, and then finally another apparently "new" one that was large enough to be convincing. It's actually a pair, but the second one is rather small.

Excellent. ~100m across? >200m deep? What a place to dome over and start building.
