Three Dihedrals.  All climbs start at the base of a low-angle ramp.   <br /> <br />Dihedral One takes the steep corner on the left. (5.7) <br /> <br />Common Denominator climbs the arete and face right of Dihedral One. (5.9+) <br /> <br />Dihedral Two climbs the bushy corner right of Common Denominator. (5.8) <br /> <br />Dominatrix is the third dihedral; it starts uphill on the right. (5.8 or 5.10)

This is a very nice pitch. The corner is steep and sustained, and it has some neat stems, backsteps, and jams. Good pro the whole way. Belay from a small stance at the anchor or lower off. A great trad lead for someone breaking into 5.7.

Actually, it is a lot better than it looks and climbs well. The corner look dirty, but it actually isn't, and you don't really get that far into it anyway.

Good fun! Good holds, good stemming, decent exposure, excellent pro (med-to-large cams), and very easy for the grade. A good beginner trad lead.

At the risk of stating the obvious, there is a lot of loose rock on this pitch. Otherwise, I agree--would be a great first trad lead.

There is some "loose rock", but I would not say there is a lot .
