Enjoying this moderate trad lead!

Seasonal Raptor Closure - Lifted MORE INFO >>>


Begin down and left from the Dominator.

Set up on a ledge beneath a ramp that leans up to the east. Climb the ramp (Class 4), then climb straight up the leftmost dihedral to the 2-bolt anchor at the top.

This route is just left of Common Denominator.


Bring gear up to 2 inches. No bolts. 2 bolt-anchor with rings at the top. Lower off, 100 feet.

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 .
