The original route was put up by Dick and Harold Webster in the fifties. Begin to the left of Half Track in a large bowl. Climb up and right to a shallow cave then out right around an obvious bulge and over near the top of Left Ski Track. Then move up left in a crack to the bolts. The original route then moved right to The Left Track and on to the top (5.6). Now Zigzag is described as moving a bit left from the bolts and straight up the deep crack above. I seriously question the 5.8 rating on this section. I may have botched the crux on the second pitch; however, it seemed a good deal harder than 5.8.
