Has to be the widest dike I have climbed on. Did it in two pitches with Stacy. The first pitch offers the only 5.7 moves (slab between a few trees for pro-no bolts as referenced below). Then neat slung horn for station and off to the races on the dike (mid 5th at most). You only need slings for pro (horns and jugs). We simul-climbed just a little with a 70m rope. Can sling the very top of the dike with a 240cm sling. Rap is just up and right and then down the 5.10 route with a 70m no worries. One rap is hidden in a hole. Pretty cool feature, kind of makes it a must.
The first pitch is the most difficult. I have never seen so many chicken heads and solid edgy features, but protection is mainly with runners around horns and didn't seem 100% solid. Someone said they walked off. I don't seem how. We did it with two raps (the second hanging on the Cruel Shoes anchor) as darkness closed in.
Don't let the R rating scare you off. Bring a couple draws for bolts down low, ~8-10 runners for chicken heads, start your watch and run up the dike. The vast majority of the route is way easier than 5.7. We simul'd it and walked off.
