In reply to Mick Ryan - Senior Editor - UKC:
They are arrows Will. You attach the rope to one of them then fire it from your bow. The arrow goes over the mountain with the rope. Then you can pull yourself up the rope to the top of the mountain. I saw it in a film with Styllvester Stalone.
...but, why so many arrows?? They must be secretly planning to ascend numerous peaks in the area. If that's the case, the damning evidence is there, in the photo, and they'll never get permits again...
