I have read that so far the LRO has detected about 200 skylights - they appear to be holes into larger spaces below them, which could be lava tubes or domes.
I would really like to know where all of them are. ASU's LRO site has all the images and multiple ways to search through them, but I don't know how to search for this. There is the RDR product search page... I don't know what that means but it looks like it might be the place if I knew how to use it.
But also, these are being actively searched for and there has to be a list out there of all of them, even a map. Does anyone know where?
