|Nat's Three Star Roof
This is a fun rail traverse, and it serves as a good warm up for the area. Start at either side of the rail and traverse to the other side, where you mantle. This is a good one for polishing some basic heel hooking skills.
If standing facing the lip of Nat's, with the lip of Nat's being 12:00, turn around until you are facing 4:30 or so and you will be looking right at it. It is the obvious, sharp lipped boulder.
A pad or two. Since the problem is quite long, you will need to bring either a spotter to move your pad(s) or do some of it unprotected. Thankfully it is only five or six feet tall at its highest, so it is really not that bad.
