Crux is the beta, work your own out because everyone's is different for this climb. The climb is amongst the majority of the boulders in Boulder Natural (an area referred to as Gandalf's Lair). It is an obvious up and left slanting lower crack the follows the arete and jugs to the top of the boulder (downclimb route). Lots of climbers find the lower sidepull helpful to use with your left hand to pull the crux move out of the horizontal handcrack.
Location
Gandalf's Lair (look for smooth, well-chalked, hand/finger horizontal crack).
