This was also true with the removal of one of the Devils Marbles to put on Rev John Flynns Grave at Alice Springs, they said they put it back and replaced it with a replica (or so it's been told).
I'm not an avid believer of the dreamtime (though interested in the concept) but when you get the goosebumps and there isn't any uncommon cause for it even the weather or the likes - plus the dead silence of the place.....
I suggest anyone that has done that to return their "curios/momentos".
Something is not right. This message is just to keep things from messing up down the road
