This delicate slab problem is located on the west face of the JBMFP Boulder, just around the corner from the Lechlinski Corner.
Starting from the edge of a shelf with your right foot on a small crack, work up and left on the improbable slab via small crimps/crystals for your hands and sloping smears for your feet to a finishing jug. A good spot is necessary on this as it has a bad fall potential, especially near the start. One star out of five.
