This is a beautiful hand crack flake, and a great place to learn some lessons about hand jamming. You can also lie it back. An optional sit start makes it significantly harder.
Location
Drive down the Vedauwoo road for about 3.7 miles from where it turns into a dirt road and turn right on road 700c. Drive down this road for about .6 miles (careful if not in a high ground clearance vehicle) and park near a road on the left. Walk into the pasture and into the pines, tending south west and walk about a quarter of a mile. See picture for additional info. This is also an alternate approach for Plumb Line Crag. To get there just walk past the wall containing this crack and follow the faint game trail as it bends around the westernmost side of Plumb Line Crag, which is the large pile of rocks to your left.
