Semi Tough

This fine thin crack lies on the right-hand section of the north end of Gateway Rock. Approach by walking into Real Hidden Valley, turn left at the "T" intersection, and after about 100 feet, turn to your left. You will see Semi Tough as the left of 2 very thin cracks/seams on an otherwise smooth north facing block. Head left in a wash, then up boulders to the base.

An awkward (balancy) thin crack/ramp start leads to finger locks to thin hands to hand crack. Descend off the back then down and to the right.

Thin to 2 inches. Pro is bomber and easily placed.
