Climb up 15' place the cam and nut, step up and clip the bolt at 20'. Make the crux move (well protected) and move up another 20' to the top. You WILL NOT want to fall from the top! Not recomended from someone leading .7 as their limit. The Webster book has this climb at 5.6x, but the bolt was added later and I guess maybe you won't hit the ground and I felt the moves were harder than .6. Of course maybe I was just scared.
Directly under the bottom of the Inferno arch there is a beautiful white streak with good holds, 50' to the right of the common hotter than hell start.
purple tcu, medium nut and a draw.
