This is located in the Cirque De Cracks on West Ridge (look at "Pool of Blood" for area description). It gets three stars, since there's nothing bad about it at all, just a fun and easy off-width. It's different from most off-widths, because you are using small edges most of the time that aren't even in the main crack.
Begin in the corner at the large off-width where the two walls join. Climb straight up and through to the tree with rap slings. I would imagine this to be a great climb for a beginner trad leader.
A mixed bag. You can be creative enough to bring anything. It can take some huge pro if you put it directly in the crack (up to a #4), or a bunch of micro cams if you choose the small cracks throughout the sides of the route. I found medium to large stoppers helpful.
Ryan Tuleja leads Duh Dihedral.
Simon on the 5.6 dihedral left of White Lightning.
Just curious how you descend this route. Any pointers?
I thought this is a great route but I don't think I'd recommend to a first time leader. I thought it was kind of awkward in spots, particularly if you try to off-width this crack instead of laybacking. It is harder than Washington Irving or Calypso (or any other Eldo 5.6 I can remember) in my opinion. Also, watch out for loose rock at the top, both in the crack and where you top out.
Don't let this comment scare you away from this route, but be ready for some stout 5.6.
I disagree with James here. Lead the whole thing with nothing larger than a #1 camalot and you'll be fine. Why drag up the weight? If you HAVE a #4 and want to place it for novelty, you are certainly able to, but the thin stuff on the sides of the crack is much more reasonable for gear.
Health related beta: watch out for the wasps about 15' up on the right side. They have a nest in the heavily chalked flake that should be the start of Zap Snack. Live and let live, they'll leave you alone. We had 6 people run up DD sans incident, just beware!
I hate to say because it sounds like more than a few folks like this route but, I think it's serious mank. Not asthetic at all. Crap rock, mediocre gear, and to make it all worse, it's surrounded by great looking routes.
I'm glad some others have enjoyed it though.
+1 on the sustained nature and interesting protection. Unless you don't mind sewing it up with small nuts and cams under questionable flakes and chockstones, bring a #4 or #5 and have at least one bomber piece in the offwidth.
Some holds are loose, definitely test them.
If you have climbing experience, you won't find this too difficult, but offwidth and layback skills make it much more comfortable to climb.
As for gear! Up to #4 needed?? If you want to use gear in the main crack, you're going to need to #5 or a couple #5s. Lesson = bring a number 5 maybe, but generally don't plan on putting much gear in the main crack. I regret that I didn't bring my C3s up. I would have been better off without my #3 and #4 and with more duplicate smaller pieces - 0.4, 0.5, C3s.
Climbed this on 10/09/16 for the first time and actually met Jim Walsh there! He said he hadn't climbed the route since his FA in 1970. After he climbed it, he said it felt stiff for the 5.6 grade he originally gave it, and I agree. We also climbed Dr. Michael Solar and Positively Fourth Street, both of which he is also credited with the FA (with Erickson). We both thought Duh Dihedral was harder than Dr. Michael Solar.
The climb itself is steep, sustained, and pretty fun. It felt more like P1 of The Bastille Crack than it did Calypso. If you plan to protect it in the main, offwidth crack, #4 Camalots are the smallest you can fit in there, and not many good placements for them. #5 or #6 Camalots would work better. If you protect it using any of the smaller cracks outside of the main offwidth (like we did), then small cams and small nuts or even RPs are all you need. I don't think I placed anything bigger than a 0.75 Camalot the whole way up.
