This is the prominant arching crack on the right side of the formation. Belay from an alcove 15 feet up from the tree at the base of the cliff. This start is accessed from a ledge a bit up the right gully. Just traverse down and into the hole.
The start has some great climbing, but is somewhat contrived, as you can step over to the ledges at any time for 15 feet. The crux is found once this "cheating" is no longer possible, and involves a long reach to a great hold and a lock. The difficulty eases off, but the pro becomes a little more sparse as you slab up the seam to it's termination and get to the two bolt anchor. It is maybe 5.5 or 5.6R. There is a little lichen down low, but overall it is a great little route.
A 50 meter will get you to the ground.
Protection
Small gear and just a few medium pieces.2 bolts and chains at the top.
There is also a second, short pitch. Step right from the belay and go up a little overhang. Go up another 10 ft, hand traverse left and go up a small roof on big holds (~5.6). 40 ft in all to another 2 bolt rap anchor (or you could just skip the middle belay). A 70 meter rope got us from the top to the bottom with only a little rope to spare on rappel.
The first pitch is reachy and probably harder than 5.8 if you aren't tall.
The first pitch seemed a little spooky on lead (I haven't lead much trad slab), but the second was more comfortable to me - like the Eldo climbing I'm used to.
