The Fazio-Rhicard/ Agee book names this route "*???????5.10b". Please correct me if you know the actual name of the route. Find the route with the bottom directions. Climb the sharp low angle rock to the actual climb. Follow the overhung pockets to the chains over the lip.
Location
Follow the trails to the Frog prince formation and at the easternmost side, after the largly overhung section, you will find what looks like the frog prince's mouth. There are three routes in here. This route is the only one on the left side.
