The first 2/3 of the route has lots of wide cracks and some bad rock, according to Craig at rec.climbing.
The upper part above the washboard is excellent (and the only part I've done). 3 pitches of steep 5.9 stemming and jamming cracks through bulges, then a pitch of 5.8 going up right, then a few easier pitches.

Start about 200 yards up and right from the start of Hairline, which is 200 feet right of the black water streaks of the Direct East Face.
