The first bolted line in El Potrero Chico. The route follows an obvious clean water streak just below a large bowl (watch out for loose rock). The first three pitches go at 9 to 9+ with run outs. The fourth pitch is the business. This takes off right from the belay at the top of the third pitch. It leads up through a small dihedral on thin moves(crux) and ends on easier rock into a small alcove (uncomfortable hanging belay). The fourth pitch will stretch your 60 m rope, so be careful about how the rope is run through the anchors. Jeff Jackson recommends this climb for a moonlight ascent in Mexico Rock.
The route is protected by bolts that are widely spaced (particularly on the first two pitches). The bolt spacing is wide enough on these pitches that it is easy to get off route, so be careful. The anchors are fixed with chains at each belay. As with any climb on La Selva, be careful when pulling your rope after a rappel -- nothing sucks more then having to ascend a stuck rope!
