Merge is the crack on the left side of the detached pillar, starting about 15 feet up above a ramp. Scramble up the low angle and get right to the base of a 4 to 6 inch off-width (left Facing). The name says it all, you can't get in the thing like you want to until you are 3 feet from the anchor, makes it quite interesting. Lay it back and go for it, the edge is pretty round and the feet are sparse, good luck.
Bring the big Stuff, 3- #4's, and a #4.5 cam should do the trick. It is named this way for a reason.
