Dirty Dipstick (Checking the Oil Direct) takes the direct line straight through a beautiful ringlock splitter, a tough boulder problem, and a pumpy finger-crack finish. Begin below the ringlock splitter, climb to it and enjoy the crisp texture of the locks. Gain a small footledge and stem left, traversing slightly to gain the next stance at the base of the business. Plug some gear and pull hard through crimps and slopy sidepulling to reach the fingercrack up and left. Hold on through interesting fingerlocking to the finish.
