The Left Chimney is easier than the right. Follow this left chimney for about 60 feet, passing a crux where the chimney tightens and steepens. After placing pro in a crack to the left (3 camalot), it is possible to break out just left onto the chicken head face (5.5 pg 13) to climb straight up to the two anchor bolts directly above.
Just left of East Chimney Right.
A 1.5" tcu in the plates and a slung head can provide some extra protection on the last portion.
