Pulling through the last few moves on “Lude Crude and Misconstrued,” a popular 5.9 located in the Black Corridor of Red Rocks, is not a particularly difficult thing to do. The moves at the top are easy. No instead, the scariest part of the climb is not the climb itself, but the anchors. So many people have put their rope through the chains at the top of the route and then proceeded to toprope or lower off the anchors that the sawing action of hundreds of ropes has nearly eaten them clean through.
This is a chronic problem at sport climbing areas across America. Chain and quicklink anchors are severely damaged due to ignorance or laziness. The problem is most visible however, in places where it is sandy. Once a rope gets sand in the sheath it literally becomes like sandpaper. The repeated sawing action of a moving tensioned rope -- especially one with sand in the sheath -- may severely damage anchor chains in as little as a matter of hours.
The question then must be asked, who is responsible for a newly damaged anchor? Is it the first ascent party's responsibility to replace the anchor? Is it the responsibility of a local guide service? Does it become the problem of local climbing conservation groups? Or are the people who damaged the anchor responsible?
There is no right answer to the preceeding question. I have personally replaced innumerable anchors out of my own pocket. I know a number of others that have done the same. We do this because we don't want to see anybody get hurt. But it's not something that we want to do.
Most of us who put up new routes or repair existing climbs simply avoid toproping directly through the chains. Instead, we use a cordelette or a double shoulder-length sling in conjunction with locking carabiners.
To the left is an example of a rope threaded directly through the anchor. Do not do this for anything but a rappel.
On the left-hand side, the anchor is composed of quick links. These are easier to change-out when they are damaged. On the right, the anchor is made up of chain purchased from a hardware store. This is more difficult to replace when damaged.
The photo on the right provides an example of a properly set-up toprope. The anchor is composed of a double shoulder-length sling, tied into a pre-equalized eight. At the bottom, clipped into the power-point (sometimes called the master-point) are two opposite and opposed locking carabiners. This is the best possible system as it meets the requirements for a SRENE or ERNEST anchor and protects the anchor chains from damage.
Checking anchors to make sure that they are not damaged, replacing those that are or providing financial support to those who will replace them, and reporting damaged anchors to individuals who will fix them is the responsibility of every climber. But perhaps the greater responsibility is to simply avoid damaging an anchor to begin with.
