This is a short section of offwidth to a bird-crap encrusted ledge into a chimney that pinches down to an offwidth.
Climb up the offwidth, into the chimney, and then up some more offwidth noting a bolted anchor to your left 80 feet up. You can either continue up the wide crack system, or traverse left to another wide crack system about 10 feet above the 2 bolt anchor, then downclimb to the anchors to set up a toprope/descend conveniently. After a one rope rap, you can then rap from the base of the climb off of the newish 2 bolt anchor with rap rings.
Look for a big flake with rounded edges to the right of Nail with a wide crack forming at its left side. There's a hueco to the right of the route about 30 feet up. Scramble to the base of the crack, and find a two bolt anchor with rap rings at the base.
Single rack of cams from fingers to big (like a new #6 Camalot).
