This entry is for completeness.
There is a route in this area that is not listed either on MP.com or in Boulder Canyon guidebooks that may have been there for 5 years or so.
Just left of Dihedral One are a few bolts that may make you wonder.
Head up easy slab to the base of the obvious dihedral of Dihedral One. Spot the bolt on the small arete or sorts. Climb easy rock past 2 bolts. You may thread a chockstone. Find a crux near a third bolt where the feet and hands are suddenly not juggy. The climbing difficulty eases and there is a crack on the left side of the arete which can take protection. Scamper up to the 2 bolt anchor of Dihedral One.
This is left of Dihedral One on a small arete.
3 bolts, light rack to #1 Camalot.
