It is mind boggling to realize this sort of thing needs to be asked, but officials with New River Gorge National Park and Preserve have had to put out a public service announcement that states: "Do not throw rocks from cliffs, it could kill climbers and hikers below."
It seems enough people were throwing rocks from the cliffs at Diamond Point that climbers reported the incidents. They said multiple people threw large rocks that could easily have hit climbers coming up the face of the cliff, or hikers down in the gorge.
Of course, there are already signs up asking those on the trails to behave like decent human beings and not throw rocks. Park officials noted "removing rocks also damages the park's natural resources by taking a non-renewable resource and removing it from where it was naturally found."
It is a shame there are so many people who apparently need to hear this message. Respect nature when you're in the woods.
