C Love demonstrating how to stem.


Climb up the obvious trad route on the Boulder Wall. It offers great stemming on solid rock.


This is the leftmost climb on Boulder Wall. Rap rings can be found at the top of the climb.


Small to medium gear.

The Independence Pass Guidebook (Tom Perkins) recommends using the rap anchors of “Grave Line”. It looked like a super insecure traverse. We ended up pulling gear and down climbing. I wish I had read Mt Project’s beta about rap anchors at the top of the climb.

The rap anchors are just out of sight from the base of the climb, a fair bit higher than the Grave Line anchors. Does anyone know if these work with a single 60 m rope?

Yes, rap works with a 60m no problem, did it the other day.

Yes, the traverse right to the bolted anchor is a bit of a gut check, especially because you can't see it until you're almost there. If you go for it, stay low, so you don't end up above it. A traverse is never really all that awesome for the leader or the second. The feet aren't awesome, but the hands are decent and get better as you go right. The bigger problem seems to be the rope drag for both climbers. Wish I had just finished the climb to the anchors at the top of that pillar.

Does anyone know the climb just to the left of Corner Crack? It felt like a 5.8--about 6 bolts to an anchor. It looked fairly new.
