A fun wandering line on crimps and friction.
A little lichen covered in parts, but it doesn't take away from the climb. A few cruxes but no one stopper move.
Wicked fun and highly recommended to those who enjoy long, techy, footy, less-than-vertical climbing.
The book says you need 2 ropes to lower, but a 60m rope will just make it (tie a knot in the other end of the rope).


The far right route highest up in the gully.


9 bolts to anchor at a sloping stance.

Very nice route, even to someone like me who usually dislike slabs! :) 2.5 stars from me. Quite well protected if memory serves. Aug 11, 2010

The other day was my first time at Yellowknife Buttress, and Ian and I were searching for Cow Patty as a warm-up before heading over to the Prudential. We headed up . . . and up . . . and up the ever-steepening gully, until it became the gnarliest fourth-classing I've done at Rumney (I'd call it 4.14a). We finally backed off (I thought about rapping), and, almost back at the bottom of the gully, we saw two bolt lines to our right. There was a little platform ledge about ten feet up, and one of the routes seemed to go up from there. Is that line Cow Patty? (We're not sure if we'll ever return after that epic gully!)

Nick, sorry to hear about your epic. Did you try to approach YK from The Hinterlands? I've always gone via Prudential. Not too difficult to find from the Pru (which I in turn approach from NW Territories).
Others might have better suggestions for approaches. I tend to go with what I know (and not be too adventurous). Oct 14, 2014

Well bolted with great clipping stances but probably a little more spaced out than many folks are used to at Rumney. Also, the bolts on this climb are real nasty looking. Not sure I'd want to a big one on them. Sep 4, 2015
