Start as for Hotter Than Hell but move left up the blank corner to a wide crack/ huge block. Surmount the block and clip a bolt on your right, then make thin moves past the bolt and clip another bolt. Move up on easier albeit runout ground to a pin in a horizontal, clip the pin and move left slightly to another pin in a crack. Follow bolts straight up on thin and delicate face moves to a horizontal crack. More thin face climbing passes a bolt to a mantle/lunge for rock spike. Traverse right to trees for anchor.
Rappel off fixed Colder Than Hell tree anchor.
When directly below Inferno, walk left until you are almost in a dirt gully. Directly in front of you will be a 5.7 slab with two bolts. This can be either the first pitch or you can walk up the gully a ways and traverse to the Hotter/Colder Than Hell start ledge.
Small to medium cams, nuts, and runners.
