This route has been a favorite of mine and most people don't have any idea of where or what it is. Are you tired of all those vertical routes at Shelf? Here is the cure.
Located at the far right side of the Gym, past where "Prophets of Rage" fell down (just look down at the river) and tucked away behind a tree are two climbs that go through 2 roofs. The one on the right is Bone n Vein.
Heelhooking and some good 2 finger pockets lead to through the first roof/bulge and to a crux mantel. Rest a few moments on the right and punch through the upper roof on big, but kind of sloping holds. Heelhook and clip the chains!
This isn't the best quality rock, but the route is steep and fun.

Great movement on steep rock! A little loose and flakey in spots. I'm guessing it hasn't been done in a bit judging by the minerals and sediment coating every hold. In its current state, I'd say 2 stars, but if it got some traffic, it could easily clean up to be 3-4 stars.
