That is an important thing to keep in mind, but keep in mind that many of these climbs follow cracks in the middle of large cliffs. I can't imagine the force it would take to move a cliff like the own shown in the link below. As others have said, you do need to assess how solid a feature like a flake is. I live in a part of southeast Alaska that has almost no rock climbing because most of our mountains are uplifted accretion formations, so a fall on a cam likely would move the pieces of the mountain and lead to a nasty fall, with pieces of the mountain falling on you as well. https://www.reddit.com/r/climbing/comments/9d995a/not_a_send_of_dreamcatcher_but_still_a_squamish/ https://www.reddit.com/r/climbing/comments/9d995a/not_a_send...
