| Jim Erickson | Lead | worked | May 1976 | E6 |
|
With Art Higbee. Nearly free ascent: established the free variations to the lower pitches and climbed the Zig-Zags all free but was stymied by a short section on the penultimate slab pitch. Erickson top-roped and bolted a free variation to this pitch in the fall of 1976 but did not lead it. Higbee's solution to the Zig-Zags is now graded 5.12d/13a and their nearly free route had some of the hardest climbing in the world at the time.
