This is actually two routes next to each other that share the start and anchor.

The one on the left is easier and on great rock. Clip some bolts and throw in a few pieces. The crux comes near the top after a bolt.

The right one is easier in the beginning and trends slightly right of the other line. Towards the top where the rock scoops out, it has a cruxy move and is probably 5.10+ish.

Both are great routes.

This is on the low angle slab immediately left of the Napa Valley chimney. Start the the right of a large tree.

A few nuts, finger size pieces, QDs. There is one bolt and a slung boulder for an anchor at the top. The bolt is decent, but inspect the rope before rapping.
