Nearing the top


Varied climbing, with somewhat tricky gear placements, up the corner to a distinct crux at a small roof just below the anchors. You'll need to employ all of your climbing skills on this one to succeed.

at least 3, .3 cams help out.

BETA below. Don't read if you don't want Beta.

1) Bring a lot of smaller cams. I used all my X4's .1-.4.

2) a .5 fits well just under the roof crux.

As others have said, emphasis on small gear for this one. This climb eats up nuts, especially offsets. I placed 1 blue camalot and 1 green camalot, and everything else was smaller. Tiny cams are useful. Of course, YMMV.

Really cool climb requiring a variety of techniques. I found it to be very well protected.
