BETA PHOTO: Three Dihedrals. All climbs start at the base of ...
The Three Dihedrals area lies up and right of Tarot Wall. It has one popular sport route, Dominator (10b). The other routes are not frequently climbed, perhaps because they all require gear. Still, if you brought a rack with you, there are some worthwhile trad adventures to be found here.
This area is somewhat disjointed. The most popular face, containing the routes Dominator, Dom Perignon, and Dominatrix, is right next to the Clipboard Area, and is easy to access.
The other routes (Curvilinear, Pillar, Dihedral One, Common Denominator, Dihedral Two) are down and left of the Dominator area.
Below and left of Dominator:
A. Curvilinear, 10-, 1p, 40', gear. L-angling crack in secluded alcove.
B. Pillar, 7, 1p, 50', gear & bolt. RFD up L side of pillar.
C. Unnamed, 8, 100', bolts & gear.
D. Dihedral One, 6, 1p, 100', gear. Ramp to RFD.
E. Common Denominator, 9, 1p, 100', bolts & gear. Crack, arete, face.
F. Dihedral Two, 6 or 7, 1p, 100', gear. Ramp to bushy corner.
G. Dominatrix, 8 or 10-, 1p, 90', bolt & gear. Corner (8) or cracks (10a) to RFD.
H. Dominator, 10, 1p, 60', bolts. Overhanging hand cracks.
I. Dom Perignon, 9+, 1p, 60', bolts & gear. Hand crack.
There are two ways to get to the Dominator area:
1. Climb up the talus field above the Tyrolean Traverse. A dirt path starts at the top of the talus. Follow the path uphill a bit until the trail splits. Take the left branch, toward Tarot Wall. After about 10', a faint trail heads off right, up the hill. Follow this path uphill to a big tree at the base of the Dominator wall.
2. Instead of taking the trail to the left heading toward Tarot Wall, continue up the hill on the right trail branch. You'll eventually reach a steep wall with a scooped-out face; this is the route Strange Science. Go left and climb up some big boulders to a flat area. The Clipboard Area is to the right, and the Dominator wall is just left of that, at a right angle to the Clipboard wall. This is the most common approach.
Dominator wall is rust colored, slightly overhanging and laced with cracks; it's hard to miss.
To get to Curvilinear, Dihedral One, Common Denominator, and Dihedral Two:
Use approach #1. Start hiking up the hill toward the Dominator area. After a short distance, a faint path heads off to the left. Take this to get to these routes. You'll see a low-angle slab; that's the start of Dihedral One, Common Denominator, and Dihderal Two. Go another 50' and uphill a bit to get to Curvilinear.

Hike the faint trail to Avalon until you reach the base of the Three Walls formation, a distinct buttress sporting a broad, low-angled west face. The colorful route Strange Science marks the northwest and lowest boundary. To the right of Strange Science is a large roof, which has a pillar-like arete on its right margin. From this reference, go left, and scramble up some boulders. This will take you to a ledge with a dead tree on it. This climb follows a very obvious bo...[more] Browse More Classics in CO
