Climb up the crack and slab to the first roof. Traverse left to the corner and pull the roof. Move up the corner to the next roof and pull the 2nd overhang. Continue up and out to the left over the final overhang and on up to the top.
Walk into the main Old Hemlock Grove area and continue to scramble up a short slab to a skinny ledge/walkway beneath the overhangs. Continue down to the slabs on your left and look for an old ring pin in a short, right-facing corner on the slab. Start at a crack that's just a bit left of the pin.
