This line climbs the bolts just right of Route 2 aka Primal Instinct. Start just right of the obvious water groove and finish in it.
Both anchors on this route are loose. This route is named Back in Black in the Gunnison Rock book. Of course it is also over-rated at 5.10c in the book.
Definitely overrated but fun all the same. It's like a slab chimney. 9+ maybe.
