This route shares the bolt anchors with the Javelin 5.11a, which is a beautiful splitter hand crack in an overhanging wall. Cello follows a left facing corner system to the left of the Javelin, which is about 75ft from the mouth of canyon on the left wall.
The crux start is quite overhanging, and is climbed with a mixture of sidepulls, underclings, and jams. Fiddling in good gear at the start is tough, so get an idea of the pieces you will need before you start out. After pulling the bulge with a finger crack, continue up the LF corner to a bolt anchor.
