Primer is the short bit excellent crack in the dihedral of the Primer boulder, on the left side of Black Wall.
Climb the hand to fingercrack to chains in the green dihedral.
This route is often overlooked because it is not drawn in any guidebooks or topos, but rather is described in the text. The guide calls it .9+ but I believe it checks in at .9. Also, it varies in size, so please, no comments about how if you're short or have carney hands it's harder. Fight grade creep!
Location
On the boulder with the green face and dihedral 50 feet left of One Hand Clapping.
Protection
Finger and hand size cams. Bolted anchors equipped for lower off.
Nice crack! And a bit sustained--would be great to take laps on for endurance (unfortunately you are mostly just training your right side).
Ya know, the finishing moves are kinda reachy and harder if you're...er, uh....and I mean, the section right before it is super tight fingers and definitely harder for those with, um.....wait, what was I saying??
