Right Twin Crack is a straight up, sustained crack with crimps, slopers, finger jams and liebacks. Really fun. It is steep all the way up and strenuous to place gear.
This route is located on the Buoux Buttress, which is the fifth crag that you will come to uphill from the Main Face. Starting at the Main Face, pass Overhang Buttress, Amphitheater, French King Buttress and The Slab and you will arrive at Buoux Buttress. Right Twin Crack is the first obvious crack, about 15 feet right of the left arÍte of the crag, there is a small boulder at the base of the climb. Walk off (climber's) left.
A 2 or 3 inch cam for the bottom, then up to 0.5.
