This route starts as a piece of cake, with easy 5.7 slab moves, but stiffens as you approach the top. I felt the crux was at the very top of the climb, between the last bolt and the anchors. Just follow the bolts.


12 bolts to a 2 bolt anchor. Be sure to use a 60m rope.... it's close to 100' to the ground.

I thought this route was 10- as well. There are lots of slab moves and the route is fun. There are not many huge jugs so a new slab climber may find it more challenging. May 1, 2014

Not sure how anyone finds this 5.10b. Seems like 5.10- to me by the last couple bolts. Jul 11, 2013

I had a great time on this route. It gets much harder very quickly - right when the rock turns white. I felt that a lot of the clips were either made from extremely insecure positions, or were slightly out of reach (5' 11", ape index +2).

Important to note that I'm also not the best slab climber out there, so that also contributed. Overall a very fun route though. Jul 18, 2011
We added 5/16" quick links with a single link of 3/8" proof coil chain to all the anchors on Catslab (except Skimbleshanks and Grizabella - they had already been"fixed" and Gus and Rum Tum Tugger..???). That should help alleviate wear problems to the cold shuts. When the 3/8" links wear, just unscrew the quick link and replace the link of chain.

Yes, it would be nice if people didn't use the anchors directly for top roping and lowering. Jun 18, 2003

Climbed here on saturday 6/16/2003. The coldshut anchors on this route are in desperate need of replacement. One of the anchors is half way worn through by people lowering on the anchors. Learn how to rappel! Jun 16, 2003
