A very good point hymac. In this case, the site in discussion is very different, as it is all too easily accessed by anyone, so the situation with artifacts is different to deep underground where only explorers get to (and hence less change of being stolen or moved.)
Unless an entire site can be preserved, things are going to go missing in its state of semi-dereliction. It's such a shame that while a site like that is still so complete, nothing can be done to protect it so in the end the artifacts which survive may well be the ones which were pilfered.
If someone could have sneaked away with an incline winder not so long ago, it would be in a better place now, no matter where! :sneaky:
