Ivory Snow is the first splitter crack right of Pillow Case. It starts off fingers then grows to thin hands. When the angle eases off the crack pinches down and face moves put you near the top. Finish on a broken crack to the canyon rim.
I have seen this route rated anywhere from 5.10- to 5.11-. The start is hard, consisting of fingers with OK feet. Once past the first 20' the moves start to flow.

A few Stoppers TCU's with doubles of Yellow Metolius Size .5 - #2 Camalot
Personally I think this climb is harder than Davidson's Dihedral just to the left. More on par with Mutiny. It may be just a boulder problem, but its a damn hard boulder problem.
Just for a little historical perspective- this was one of the Forks climbs that was put up pre-TCU's (smallest cam at the time was the #1 Friend). So Paul protected the crux on wired hexentrics and wired SMC Camlocks (anybody ever see one of these- funky!).
