Amazingly powerful climbing on a steep roof.

Start low in the cave and move up and out with your best heelhooking, pinching, and core tension techniques. Slap for a good spot on the lip and then prepare to mantle and creep up the slab to the top.

Also try the much harder Thunderdome variation that continues out right.


Straight uphill from the Yosemite Highball boulder. Look for the huge black charred tree that is 10ft. from the problem.


Crashpads and a spotter or two


This thing keeps breaking. The good right hand in the middle of the problem has broken, leaving a poor pinch. The move up to the sidepull before the lip and the next move are now quite difficult. Sep 5, 2014

I have heard people say this feels burly now: Ben, Jesse and I were out there last fall and broke both the left hand thumb catch near the lip and a nice foot for rocking over onto the slab. It definitely felt harder after that. Sorry! Oct 26, 2009
