Continue downhill from Mushroom Rock for perhaps another 70m to the end of a rocky promontory (not far from where the rough climbers' track - used to get down to Isotope Wall, Angel's buttress or the North Wall of the gorge - swings hard left, looking out, and into and through a narrow rock cleft).
Abseil 35m over the route, angling slightly leftward/east to belay in the steep gully off the east side of the buttress.
Engaging climbing up past 2 carrot bolts and around right onto the front of the buttress and a fixed hanger. Then slab up tending rightward past four more carrot bolts, a fixed hanger, then the arete past a final carrot bolt to belay.
Hidden from view around the arete at the end of the ledge.
Climb onto the slab, up chimney and onto ledge (probably best done with a rope). From here you will see the steep finger to hand crack. finish at DBB as for BACINT.
Pull onto ledge however you feel to the black often seeping corner. From here move L into century box with some difficulty. Up to undercling, punch out L and up face passing 3 fixed hangers to DBB.
P.1. Start up easy chimney with loose blocks at top, travers L passing a bolt before stopping at the vertical crack (semi hanging belay).P.2. up crack (seeps after rain) to finger crack in corner and R curving crack to finish.
Alternatively start up Abracadabra, then move R and finish up P.2 of BB. this allows you to do the route in 1 pitch.
