This is currently the fourth bolted route from the left on the scale wall.

Getting past the first two bolts is definitely the crux, so be confident in your abilities.

Climb up through a committing first section to easier climbing above. Past the second bolt, this route is probably a 5.8.


6 bolts to a 2 bolt anchor.

Somebody bolted a sixth bolt a few feet from the ground to help protect the crux move before the higher (now second) bolt. The route seems like a 5.8 after the crux.

This route is now rebolted and ready to go thanks to Brian Poulsen! Thanks Brian and ASCA for providing the hangers and bolts to fix the ones that were previously vandalized!!

bolt #3 or #4, can't quite remember is a little loose and the nut is rusted so I couldn't tighten it. Just a note to the wise.

Decent route not R rated in any way the lower bolt seems ridiculous but the first moves are the crux.... still the landing isn't that bad if you did happen to fall with your feet 2' off the ground.

Super fun route! good to learn sport on but not a total walk in the park. The crux is about 5.10 but after the 3rd bolt its a 5.8 cruise for sure.
