Monkey and the Engineer

Climb a slab to an obvious roof (crux), and trend right to stand up. Then go left up the prow of the steepest and longest section of the cliff. Scratch your head to get out the roof, and then get a good rest before launching up the headwall above, which thankfully is a bit easier than it looks.

This ascends the tallest, steepest section of the cliff.
