This is a fun route especially on lead. The guide book says that it is a 5.10a but I would give it a 5.9 just because the main face is mostly slab with great stances and plenty of places to rest. Also I climbed this when the rock was wet inside the crack and it was still an easy climb for me. The crux is at the very top when you have to pull around and behind the prominent point.
The only bad thing about the route is that rope drag is almost unavoidable especially if you're setting a TR.
This is the first large dihedral crack on the Royal Arch wall
This crack uses a range of different cam sizes. I used (2) #2, (1) #1, and (1) .75 BD Camalots along with a #1 metolius master cam and a .5 link cam. There are also two bolts at the top for anchors. no chains
