BETA PHOTO: Chuckwalla, 5.8, Potrillo Cliffs, White Rock, NM
This is route #22 in the on-line guide. As noted therein, a chuckwalla is a "large lizard with the interesting defence mechanism of crawling into a crack and inflating itself." Start under the large, thrillingly wedged, guillotine-shaped chockstone and work up into the chimney. When in doubt of where to go, just recall the route's namesake and stuff your self in there. When the chimney narrows to the point where your head starts getting wedged, move out of the fissure onto the face to the right and follow the dihedral to the top.
Near the left-middle of the southern cliff.
Standard nuts and cams to #4 C4. A #5 or larger could be used, but is not essential. Popular to top-rope; a 2-bolt anchor, reachable from the top, was recently re-installed (please don't sling the trees anymore). There's also abundant opportunities for a gear anchor on top if you like.
