Climb a few moves off the deck to reach the slab proper, then follow the left-hand line of bolts up to the top.
Find the left end of the Zulu Wall where there is a large slab with a pair of black streaks running down it and a lot of funky vein-like ridges. Voodoo Child is the left line of bolts up this slab. Start in the obvious crack/features directly below the bolt line.
New ASCA anchor on June 13th, 2015. This Anchor replaced a rather manky thing. We thought it was 1 1/4 inch compression bolt and one rusty wedge anchor bolt, the 3/8 incher turned out to be a compression bolt as well. Both pulled VERY easily.
