Just to the right of 420. Starts on the right up the two bolts to the shelf. Crux in the middle of the climb.


Move up trail to Chalkporium. When you get to the wall look right for the two bolts that take you up to the ledge. The two routes on the right share the same start, at least for right now. You can belay all three climbs from the ledge.


Bolts with musseys. Shares the anchor with "High Class Dive Bar".

The 5.10 climbing is in the middle thin section. A couple of delicate moves in a row and the rest is easier. As of 4/24/16 the lower section needs some big time cleaning. Very mossy and mungey. The route is cleaner above that. Apr 25, 2016

If it's a 10a then it's a very soft one, but the quality is good and very closely bolted too. Jul 17, 2017

At the 7th bolt, don't cheat and go right. Stay right on the bolt line. Sergey Shevelev, maybe you went right at the 7th bolt? Sep 18, 2017
