I continue above this pitch by linking into Little Finger, then climbing through LF's direct finish overhang, yielding an excellent 3 pitch 5.7 PG route.
Bill Route itself is an excellent intro to the friction climbing on Roger's Rock. The pro is abundant compared to many of the routes, yet spaced apart enough to give initiates the heeby-geebies on their first go. The museum-grade 1/4" rivet just below the belay anchors is an amusing(??) reminder of "how it was done" back in the day.
Once you've deciphered the initial moves, spider-crawl up the slab following a drunken line of bolts to a two-bolt belay.
A second pitch has been added, though I'm not sure where it goes. Note that the rock pillar lying on the slab above the anchors is part of Little Finger Direct which is 5.8X.
About 50' right of the obvious crack of Little Finger, just right of a high bump along the base ledge, at a tiny right-facing corner that leans right and fades out 10' up.
Descent is via rappel with double ropes.
Mostly bolts, but the initial hard move is protected by a brass or small wired nut. Linking to Little Finger requires a full trad rack.
Make sure to bring double ropes, as the rappels are very long.
