The Bihedral Area Rock Climbing
Bihedral Rock Area.
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 photo
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)
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.

Ticks have arrived. Despite a tick check of clothing and ankles, a baby tick made it home with me and was discovered inside my shirt (4 layers deep). Be thorough in your tick checks!
