From Site 16, walk about 30m up the hill to the jumble of scrappy boulders and skirt to the left. A short and wickedly left-curving offwidth, capped by a small roof, presents itself.
Set a top-rope off of bomber boulder anchors on top, lead it (nothing bigger than #4 camalots required), or suck it up and boulder it out...
Excellent after-dinner or after-breakfast entertainment (for spectators)
This is a traverse around the outside of the Lake Catani Shelter. Begin by standing inside the hut and the problem commences as you step directly out onto the rock façade of the building in the left direction. Continue around all walls of the building until you return to the door and can finally step back inside onto the ground. Whilst not technically that difficult it is an epic endurance problem with many pinch grips. Use of the wooden eaves is forbidden and you cannot sit on the window ledges for rest. Link up with a second loop of the hut by traversing the doorway and beginning the problem again.
The route is approximately where the 'e' in choke is on the topo in the 2006 guide.
Where the track reaches the second tree with right pointing arrows on it, head to the left and downhill. There are several gaps between the boulders (cairn) and a short step down through these leads to an open area. On your right (facing out) is a left leaning corner crack.
