Twin Crack- 5.11a/ Ignore anyone who tells you this was ever a 5.9! even by old school standards. The roof move required to get up and into the sustained crack above is as tough a move as any required on the free single pitch crack routes in Zion. The wide right crack offers no assistance through this crux. Once you complete the crux move, you will continue on a sustained finger crack above. It is easy for your cams to become flared in this crack at the start. Another bolted station awaits you above and again, double ropes are needed for the rappel.
