Why yes, I remember Pan-X, and that was just the stuff that was readily available. A neighbor was a lt col in the air Force, in charge of maintenance of the local u-2 squadron. He offered to arrange an overflight of our excavation, averring that they could tell whether we were using square point or round point shovels in our dig. I don't know what film they were using,but it probably had superior resolution to Pan-X. This was all part of their training routine; they had already photographed all the golf courses in Arizona, so why not do a cliff dwelling?

I would hope that beside the crowd sourcing, someone in that search effort is involving the military. We did that on the operation i referred to previously, and something flew down from Scott AFB and zapped our search area. They were not at liberty to discuss the technology involved.

I'll bet that experienced photo interpreters will be more productive than the public at large....
