The route is a fun 5.10c which is shaped like a dinosaur's back, just to the left of Hostile Crankover. The book claims 5 bolts, but it is, in reality, 6. Use the left side of the arete as the most obvious route next to between the 4th and 5th bolt.
Location
Just left of Hostile Crankover and Energy before Ecstacy (two roof routes).
