... 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. -------------------- ...Tom

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

Is it really impossible to dig out something from the black?
So this can only be a fantasy... What I did was an attempt to enhance some features that were already visible in the image shown here on the right but that also come out from the original one. Note: I know that it has already a name but Cernunnos, the Celtic God of Fertility, Life, Wealth and the Underworld sounded just perfect for the occasion... -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

It's mostly noise, but on the scale of the whole hole, the upper part of the circle is lighter than the lower part. This might be the floor showing. They just need to increase the exposure time for the next pass. -------------------- Antti Kuosmanen
