|a. The Uberfall
Climb the face three feet to the right of Boston without using any of that climb's holds. Holds on the right side of the face belong to Fitschen's Folly so stay left. The climb moves through a several inch wide overhang toward the top and ends directly above the start. Be prepared for lots of pebble pinching and subtle moves. It's worth the time if you already have a rope up nearby.
Three feet to the right of Boston and just left of Fitschen's Folly near the triangular kiosk in the Uberfall area.
Climb this route as a top rope set up near the top of Boston. There are essentially no possible gear placements on this route (maybe you could get some micro nuts in under the little roof 20 feet up). I suppose that one could place gear on Boston (three feet to the left), but it would ruin the flow of the climbing and would still likely bring the risk of inadequately protected falls.
