Walk up the four - five gully as if you are going to Eyetooth. When you get with in view of Spire Four you will see a small roof about half way up on the south/southeast side. Climb a series of cracks and flakes to the small roof. At the roof climb out right to a hanging belay with chain anchors. Hence the name "Hang a Right at Fourth Avenue". From the anchor move to the right and catch the small seam that continues to grow into a larger crack as it goes up. Follow this to the top.
I use everthing from small brass nuts to a number 4 friend. In fact I usually take one of each friend and I take two number 4's Up high a person could use something bigger after the high bolt in the off width of the second pitch, but I never seem to. I've climbed this route several times.
