This is a Luebben/Brink Poudre Canyon classic. The crux is right off the deck, tackling steep, overhanging tips-fingers. The grade is kept at 11d due to decent feet. After the intitial crux, the crack gradually widens...thin hands, hands, traverse, wide hands, fists, and ends with OW. Superb climbing.
See directions to the Sentinel. This line cuts the Northwest face (go west around the formation when approaching). Walk off.
Standard rack. Bring at least 1 #5 Camalot and 1 #6 (more big gear depending on your comfort level with OW). Big-bros would be very challening to place as the rock on the inside of the crack is disparate.
