One of the stand outs of the U-Mound area.

Start matched on the left facing edge/jug at shoulder level. Pull up to a sloper with a thumb catch up and right. From here there are at least 3 ways to do the next bit all of which are about the same grade depending on what you are best at. You can back step either way and reach up to either of the side by side edges with one hand or the other or you can heal hook by your left hand and rock up to the edges. Next make a difficult pull to the knob edge out right then up to another small edge and finally a bigger one. The holds for the top out are pretty small so if you don't scope it out first there could be some groveling involved...there maybe groveling anyway.


The east end of the corridor on the north side.


Pads and spotter. You will want a couple of pads at least for this problem, one on the ground and one draped over the boulder and your spotter standing on the boulder to keep you off the higher one. That said it seems a pretty safe problem and I've never seen anyone take a really bad fall off of it.

Best problem at the Mound. Much less scary now with pads. Feb 28, 2009

This is a great boulder problem. Dave showed me this problem on a small trip to Albu, struggled day 1 sent day 3. Do this problem Mar 11, 2009
Hmmm, I'll have to check out the chalk marks but my recollection is that we used to do this one starting a couple of moves left of the obvious chalked holds. It was considered a traverse up and right.

Murray was the first to ever nail the whole problem (that I saw.)

The easier stuff on the right hand wall we've always called Burger King due to the proliferation of problems and eliminates to be had. Mar 11, 2009

As of early Feb 2012 a hold has broken on this problem. It used to be a good left-hand crimp about 10 feet off the ground, now it's a pretty good pinch if you get it right. Not the crux of the problem, so the grade shouldn't change, but it still sucks. Seems unlikely it was simply pulled off, looks more like it was smashed with a rock (can be reached by standing on the small boulder next to the problem). This happened at around the same time as two other likely related events:
1) Someone took a dump at the base of this problem and left feces and toilet paper wads strewn around the ground. There was a lot of it and it really stank (fortunately we had an extra doggy shit mitt from the trail head).
2) The V1 arete on the west side of the Brett and Jill boulders was smashed (see description in that section).
Hopefully this is not the beginning of a major defacement of U-mound. Feb 6, 2012

Just got on this again yesterday. Unfortunately, the broken hold really does decrease the quality of the problem. Tore the pad off the tip of my left ring finger moving off of it. Be careful to move onto and off of it as statically and precisely as possible or you may get an unpleasant taste of what sharp granite crystals can do to your skin!
I originally thought it was a 4-star problem, now I give it 2... Feb 16, 2013
I agree that the broken hold has changed the nature of this problem. To my mind, the top out is considerably more terrifying than before. And I too can attest that it will draw blood! Dec 5, 2015
