Description Suggest change

The Bihedral Area includes at least 4 sub-areas: The Bihedral, The Riviera, the Left Side and The Lower Tier. For organizational purposes, this is subdivided here. This
may help.

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.

Getting There Suggest change

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".
