From the ledge at the bottom of La Creme De Shorts, step left to the arete and climb over a bulge formed by a loose-looking (but apparently solid) block. Follow weaknesses diagonally up and left to a clean reddish face. (The reddish face is above the ledge system that connects the top of the initial La Creme corner with the belay for Storm Mountain Stupor). Climb the crack on the reddish face and work more or less straight up over several bulges to the large ledge on which Layback Crack ends.
When we did this, my 9- and 11-year-old partners rated it 5.5, but it likely would be a handful for a novice leader, hence the rating. Given the long history and popularity of the "Island," this line may have been climbed, but we'll take the glory (if not the FA, can we at least name it?).
Location
Left of the La Creme De Shorts/Layback Crack corners (and their variations) and right of Storm Mountain Stupor. Rap from bolts atop Layback Crack or walk off.
Protection
Standard trad rack. Protection is tricky but adequate so long as the rack includes cams and long runners. No heartburn here if someone wants to add fixed gear. Two-rope rap from bolts atop Layback Crack.
