The Bihedral Area rock is typical Boulder Canyon granite climbing. Generally less than vertical on bullet hard grey granite. Good friction with a high concentration of slopers, both large and small, and positive incut edges. The Bihedral crag itself is identified by a huge, left-facing dihedral and sits on the north side of the canyon. The dihedral is split by a prow about 1/2 way up. The Riviera is located down & right of The Bihedral. The Left Side is located to the left of The Bihedral. The Lower Tier is located below the The Bihedral (Upper Tier) upper tier.
Drive 7 miles up the canyon (zero at the bridge a la Rossiter), park just past the Riviera at a pullout on the right, or there is shady parking on the left side identified by a west-facing "No Camping" sign nailed to a tree. The huge, left-facing dihedral of the Bihedral is obvious above you. Cross the road, walk down a bit and pick a line up a boulder field and scoot left around a short broken buttress. 4th class it up past some trees on your right and gain a nice ledge at the bottom of the big dihedral. There are a few good routes here, but the most well known is the 2 pitch Bihedral Arete, which Rossiter so obtusely refers to as "something of a classic".
This route is one of two routes up the striking headwall that caps the Bihedral.This climb can be seen easily from the road on the top 1/4 of the Bihedral. It starts in a overhanging handcrack for a few meters, gains a small square pod/cave, then exits the feature on the right hand side in sustained tight finger-locks and sidepulls, going up to a tree at the summit.P1: Approach via the climb Rhodian Shores, Crack Variation, or Bihedral Arete.
