                     Rappelling Methods for Climbing

                     multipitch rappel. Climbers use multipitch rappel-  rope, always protect yourself by tethering to the
                     ling techniques to descend from long routes, nor-
                     mally with two ropes tied together, allowing them
                     to descend the length of a standard rope (60 or 70
                     meters) on each rappel.
                        The first thing to check on a multipitch rap-
                     pel is the condition and soundness of the anchor,
                     as in most cases the rigging will already be in place,
                     having been left by a previous climbing team. The
                     most common anchors will be two bolts, a single
                     tree, or a solid, wedged block of rock. If I know I’ll
                     be descending a long route via multiple rappels, I’ll
                     bring extra nylon webbing, rap rings, and a knife,
                     in case I need to cut away a nest of old slings and
                     re-rig an anchor. On obscure climbs in Yosemite,
                     I’ve come across old nylon webbing bleached pure
                     white by the sun, only to flip it over and find the
                     other side bright red. Over time UV exposure will
                     weaken nylon and Dyneema/Spectra webbing,
                     so carefully inspect any existing slings you might
                     decide to use. If the sling is stiff and the color faded
                     from UV exposure, it has probably lost a major-
                     ity of its strength. Also, if the sling shows a burned
                     (blackened) or glazed mark where a rope has been
                     pulled across it, the sling should be retired, as the
