This fine line spawned the now classic, and much more popular Goliath. This was the original line up the Towers prominent prow, turning left around the arete at the midway anchors, and continuing to the top along the golden NW face just left of the hanging arete (the upper half of ZWW).
Climb Goliath to the midway anchor, then turn the arete, and climb the right-most set of anchors to the top of the tower.
Many, many bolts. Use a long sling at the midway anchor.
