This route climbs the arete to the left of the unknown 5.9 dihedral. Follow the line of 4 bolts up the arete, then run it out up and right to the obvious, bolted anchor (shared with the two unknown routes to its right). Typical South Platte friction with a couple of good holds thrown in.
Location
Just left of the obvious, right-facing dihedral of unknown 5.9.
