★★★ Corvus 24

One of the best lines and climbs at 'The Cloisters'. Start at the left hand end of the wall, below a thin crack. Bouldery moves to start, then layback to the alcove. Swing left then move quickly up the crack before you pump out. The route takes a variety of gear, but the business is a steep finger crack which likes medium wires and/or green and yellow aliens (0.2-0.4 camalots). For convenient dogging, pre-rig an anchor over the lip with a 15m bit of rope.

Although these days there are a number of excellent sport climbs, the original ascentionists were staunchly traditional, having this to say:

"We, as discoverers and first ascensionists, have not and will not tolerate the use of bolts, pegs, shady aid or chalk. Attempt to use any of these and be prepared to answer to us. We have respected the natural state of the area and expect that you will also."
