Approach the North Slab (which faces west) from the top about 50 yards north of the north parking lot. Scramble down to the base from the south. On the right side of the slab, right of "Leaning Seam" and "North Slab" are two more incipient vertical seams. A scattering of marginal holds will test your concentration and footwork as you climb past these. It's over much too soon, however. Traverse off right or wander to the top.
Bouldering pad to cover a rock rib on the right. Spotter optional.
