Todd Graham at the crux move of Pumping Groundwate...


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.

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.

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).

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.
