Thought of a few more...
14. Trusting a cam placed in a glassy smooth parallel crack, only to have it tear free under less than body weight. Cams need a rough surface to initiate expansion. Treat greasy smooth parallel cracks with the same suspicion as flaring ones.
15. Watching the end of the rope disappear as your leader, out of ear shot above, quickly sets a belay and takes in rope. Why aren't you tied in to your end? On an overhung or traversing route this could be more than just an inconvenience. Excepting certain circumstances, climbers on a multi-pitch, should not need to untie if they have enough ropes.
16. Watching your falling second (or third) pendulum into an arête. Leave enough gear in traverses to protect followers. Don't let your second get so carried away with cleaning they forget about your third.
17. Finding sheath damage or worse, from a top rope over a sharp edge. Extend top rope anchors over the lip, and pad if necessary. Make people walk down or abseil rather than lowering. It also might be necessary to set gear, mid-route, to guide the rope past sharp blocks. Consider if the route lends its self to top roping, and perhaps move on.
18. Rapping off a single piece, only to have it pull. Never, never rap off a single piece, unless it's a huge tree or bollard, and even then think carefully. This practice of backing up the single "bomber" piece with other, unweighted, pieces, and then eyeing the loaded piece while the first descender heads off is total myth, and will not guarantee your safety - it's put people in hospital including a climber I know. Don’t be cheap with bail gear.
20. Belaying the leader, unanchored, too far out from the cliff you are slammed into the wall during a fall, possibly releasing the belay, and, due to the angle created you may rip their first few pieces. Stand close to the rock. Put a helmet on if you're worried about rock fall. Tell your leader to get an omni-directional in first up if you must stand back.
21. Top roping off a sling. Are you crazy? The friction of your rope moving against the sling material will slice it like a knife though butter. But how about abseiling off a sling? A practice wildly used. However consider movement such as swinging into the overhung or traversing route to clean gear, kicking out to avoid an obstruction, or leveling the ropes during the decent. What is this movement doing to that sling? Is it worth the cost of a leaver crab?
22. Building a belay with trad placements all in the one crack, block or feature. Said feature fails, resulting in total belay failure. When faced with a "perfect" splitter it can be tempting to stuff it full of cams and shout "on belay". Don't put all your eggs in one basket.
23. Onsighting a route without enough draws or slings resulting in forced run outs, rope drag from hell, walking cams, wiggled out nuts, a scary solo or worse. Consider how much slings weigh. Take them all, even if it looks like a straight line. |
