Superb cracklet and face to the right of "Flashflood"...

Have heard trad complaints due to the stellar crack with bolts on the bottom...but I enjoyed clipping from the locks...

Maybe easier if you are taller. 11d felt right to me.


Rightmost of the 3 routes on the pillar in front of powerhouse. Look for a splitter crack on the bottom.

I found this slightly harder than Flashflood (I'm 5'9"). The chalked triangular flake between bolts 2 and 3 is flexing pretty badly as of 11/2017. Nov 5, 2017

Its really a one-move climb. Get big jug, get feet up, and lunge with left hand to flat edge, then crank up and right to good edge. Jun 22, 2016

This route is probably 11+ if you're tall and can climb technical face well. But for shorter folks I think it's solid 5.12, if not harder. I think Sex (5.11d) and up-canyon is harder (at least for me). Mar 10, 2014

Guidebook says 12a. So do I.

But maybe that's because I climbed it in the shade on a 38 degree day. In any case, I thought Flashflood was only slightly harder. Dec 28, 2011
