I'm not a very serious climber but have friends who really are. Apparently the lessons from reading this book: http://americanalpineclub.org/p/anam http://americanalpineclub.org/p/anam are that the vast majority of climbing deaths are due to one of two reasons: 1. Belaying off the end of your rope (Always tie a safety knot!) 2. Not wearing a helmet. So, yes: climber error.
