Start sitting at the base of the arête between 'cryptography' and 'classified'. LH starts high on a thin side-pull pinch on the left side of the arête, RH down low in a 2F pocket on the right side of the arête. Crank off the ground and bust way up and right to a RH undercling. Work up the arête to match and finish on good holds off to the right. The dismount is treacherous because of the rock behind/beneath you - be careful !
A true SDS or it's easier. Shorter climbers may need to slide an extra pad under to reach the LH start hold.
