Humbolt

The best warm-up on the Early Wall, and one of the best routes at the grade at Diablo (that's not on the Winter Wall, anyway). Its name hints at the first three bolt placements near the crack, without which it would see much less traffic. Start on a big block and climb a finger crack followed by a mantle, then crimping and edging on the thin face left of the arete on small edges to the anchor. This climb is thinner but not as steep as most at Diablo. Fun, high quality climbing.

Just left of 2 Wheel Drive. It's climb #8 in this online guide photo

9 bolts to a 2-bolt anchor.
