BETA PHOTO: Jon Enterline just after the crux traverse on Josh...
Main Street Crack ends below a small tree/bush where most people escape right to Riverview Ledge. Josh's Hump continues straight up short slabby section of rock below The Great Roof to a stance in the left corner under the roof. Microstoppers or a #00 Camalot buys you some protection here before a scary traverse to the left out on a prominent, light-colored arete. The is the arete where Josh Laudermilch (seconding my lead) stopped to hug and/or hump the arete. Use a long runner on the gear in the corner to avoid rope drag on The Great Roof above. We regularly do this route in one pitch with long slings, especially under the roof. Communication with your second is difficult when you are on the summit and your second is under The Great Roof. Note: You can also start on Witches Brew, and move right up under the Great Roof before you head into the Chimney.
Near the left side of the Main Wall about 30 to 40 feet to the left of the Library dihedral look for the long, left-leaning crack system that starts just to the right of the small buttress. (The other side of the buttress near the tree is Witches Brew.)
No fixed gear. Extra small stuff required for the crux moves under the Great Roof.
