Dial 911 

It seems that this route should go under Snake Buttress and not Central Endless, though Snake Butress and several other areas could also go under Central Endless.

EDIT: Thanks for moving it.

Extremely sequential, thin climbing. The lower portion of the route which leads to a horizontal break beneath the first roof felt around 12c. This section involved big reaches off of hand foot matches and ended with a large deadpoint. Rest at the break and psych yourself up for what lies ahead. A long lock off to the glued on flake and a hard clip off a slopey rail. Then the redpoint crux, a blind toss to a crimp over the second roof. Savor the easy slab above.

Definitely harder than 12c to the break! the move to the slot is the hardest part of the whole route. Felt 13a to the break then you get everything back and it's maybe 12ft of climbing and you're done. Hard for the grade (for me). One of the best though!

I agree that the section below the first roof is harder than 12c; it's the meat of the route with the hardest moves. You can get everything back under the first roof, and the moves past it are 12a, tops. Insanely cool route.

After a re visit I will admit like most that getting to the break under the first roof is 12d maybe 5.12d/5.13a. But being 5'7" I was not able to rest comfortably due to the distance to the footholds. I worked this climb for 6 days over half a season and continually steeled myself for the section after the rest and through the two prominent roofs above. I worked it in typical late spring conditions and the day I redpointed it had been raining eight hours prior and the fog was as thick as pea soup. I was never able to make the section from the rest any easier than 5.12b or 5.12b/c so let's say 5.12. I found the clip from the sloper rail very taxing. The blind sun-in-your-face deadpoint over the final roof to a three finger crimp then match nearby on a tiny credit card edge then huck to a flat rail was worrisome on redpoint (and my mental crux) but perhaps 10+/11- on the dog. When I sent this climb I had never been so mentally at my limit on a rock climb and therefore Dial 911 is my favorite sport climb.

Yeah. 13a by itself to the break, in my opinion. Out to the sloper rail is powerful, the moves over the roof are easily 5.12 and not over until you have moved out left past the last bolt. I'd say 13a to the break...then 15-20 feet of 5.12/mid 5.12 and then 5.10 to the anchor. I don't know where I got 12 feet from.

Best 13a I've done anywhere.
