Start up the overhanging chimney located in the corridor just after a third class blockage. Follow the thin seams until the bolts are reached. Somewhere between the second and third bolt, commit to the north wall, and climb past the slabby topout to a ledge with bolts and chains. Rappel (lowering will shred the rope).
This route is located in the corridor behind the 200 foot flake on the left side of Mushroom Massif.
RPs and TCUs for the bottom of the crack, a #0.75 Camalot, and 4 bolts.
