The first pitch I feel was maybe 5.8 or 5.9 with sparse placements. The move right on the second pitch to the rounded ledge I feel was 10+/11- (compared to the slabs on the right section). I may have traversed too high though. The slab above the ledge is some fun spicy friction slab. I believe the third pitch is the final pitch of Greenhorns.

When I climbed this I ended pitch one to the right of the rounded ledge, then climbed the slab and the finish of Greenhorns. I would suggest however linking all the way to the top of the slab above the rounded ledge for a fun long first pitch.

I agree with Joel, the move out to the ledge where it rounds over feels like 10+/11a. It was harder than any move on Thin Slice or Slide Action Traction, both of which get 10+. I wouldn't reccommend that last pitch past the bolt until we get it replaced; one bolt for the whole pitch of what appears to be insecure climbing.

I thought the traverse move was solid GM 5.9 (meaning I would have rated it 10b if it were anywhere else). That said, both I (at 6'2") and my wife (at 5'2") thought it was 5.9 - so at least it is not height dependent. Just very thin and scary.
I also second the idea that the face above this rounded ledge is quite runnout and that the lone bolt is less than stellar.

I believe the topo shows that slab having two bolts where the other bolt is supposed to be higher than the one already there. When I was climbing however I didn't see any obvious remains of an old bolt.

A good moderate link-up is Pinhead -> Conkomatic

The traverse move was definitely exciting. After falling, it felt like VO+ at groom creek, the scare factor being significantly reduced. Absolutely recomended for on an early season morning, shady and crisp!

this route was awesome! that last bolt was hilarious! still only one bolt at the top where the topo says two.
