Unknown with Two Bolts

On Aug. 9, 2011, I began in a short, left-facing dihedral, down and to the right of the other routes on the upper-left tier. I climbed the dihedral (crux) and continued up a narrow slab protected by two bolts. At about 100 feet, I missed the two-bolt anchor at a ledge on the right. Instead, I continued up dangerous, loose rock. I eventually left an old sling on a block and rapped, finding the correct anchors on the way down. The best part of the climb is at the bottom.

This route appears to be the right-most worth climbing on the upper-left tier.

Two bolts, plus SR, to a two-bolt anchor at ledge on right.
