Some guy from WA psyching up for the crux of Pumpi...


Basically located in the power plant parking lot...not the prettiest location. Thank god the rock and routes make up for the atmosphere. The cliff is littered with strange old DWP concrete and rebar and well as glue filled cracks. The best routes are in the hard 5.11 - 5.12 range.

Getting There 

walk along middle power plant road to the working power plant.

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....[more]   Browse More Classics in CA

Note to people who get in a dither about glueing: this entire cliff appears to be bolted and glued to the canyon wall.
