But it's also a warning to us to inspect, reinspect, test, and overprotect all of our gear and protection and anchors. The first picture is a toprope anchor on bolts and hangers at a crag in Colorado. Note that I extended the lockers over the edge so that the rope wouldn't be dragged over any sharp rock while belaying up and down. I also added in a tri-cam and sling as a backup in case of failure. The tri-cam is wedged into an hourglass section of crack and took a bit of care in extracting. I knew it wouldn't fail.
The bottom line in all this is of course, to BE SAFE! Who would ever imagine 8 quickdraws in a row failing?
