Was thinking about this boulder the other day, someone suggested it should be trundled. Belaying under it is quite worrying, knowing that it has moved recently, and doesn't seem to be that well wedged in there. If it was going to go of it's own accord, I suppose it would be when a climber is walking around on it (but really, more likely during heavy rain), and a belayer would have no way of getting out of the way. Any thoughts chockies?
It is worrying but I think it's ok. Probably require a few 5T jacks, worth a go tho.
It looks like part of the rock it was sitting on collapsed which allowed it to slide. It must have re-wedged itself to stop.
