As a member of the Sensitive Climbers Against Trundling (SCAT) I am appalled at your behaviors. It is one thing to accidentally knock off rocks and boulders but quite a different matter to intentionally knock off xenoliths which have been perched on the abyss for millenia. Who are you to decide when a rock is to fall? Are you God? The next thing you know we will be trying to create kids in a test tube. Personnally I find a monolith sitting on the edge of the nothingness one of nature's most beautiful phenomenons. Thanks to our members dollars we are educating students across the country about the destruction, dangers, and stupidity of the insiduous act of trundling. I can see from the posts here we have a long way to go. So remember to hug a rock and not shove it.
