The South Nose exit is a popular way to top out Chimney Rock. Several routes will get you to the S Nose. “It Ain’t Hay” is probably the most popular route to gain the S. Nose. From the belay ledge (gear anchor) identify a single bolt on a clean face. Plug a couple small pieces of gear and then make some delicate moves to get to the bolt. Continue up easier terrain to a two bolt anchor at a ledge. Unrope here and scramble to the summit or do another short pitch. There used to be a large block and a piton, that protected one more difficult move. No idea when this block fell (sometime after 2017).
