This is the big prominent corner leading to and past the right side of the giant roof on Lower S Curve, left of the Melting Point bolt line. Easy climbing up the corner ends at an obvious hand rail diagonally right out of the corner. This is the crux. While well-protected, be circumspect about how the rope runs, lest you end up with horrendous rope drag. The hand rail turns into a small ledge which hooks up with the last 20 or so feet of Melting Point. Ruckmans' guide shows another finish, but I can't quite figure out where it is in conjunction with the line we did.
Location
Rap from the chains on Melting Point (60m rope necessary).
