Sit start in the middle on the front, vertical face on a descent ledge. make a far move up to a flat ledge and then into a pinch with a finger-catch bump on the long hollow tube/rail/ledge extensions above. they seemed solid, but I wouldnt try some ridiculous swing on them (i cannot for any reason see why you would but its best to say something...). move up to the top out via good hands.
In the middle of the vertical face under the long hollow rods/ledges/rail/flake thingies that sound like xylophones...
