A thin pencil touches the rock at about 3 places on its fall from the rock band of the rim of the canyon. Otherwise, it hangs free from the face. Follow it, delicatley, sometimes using edges and ice blobs on the face if needed, to the final rock headwall and pull through to top. If it's fat enough to lead, stop at ice and V-thread down.
Between #5 and #7, obviously.
Screws, when in, otherwise TR with long webbing anchors.
