Traversing the break is fun. Trying the start to the right hand side of the wall, but having difficulty leaving the break. This would give a start to a hard route up the wall right of Ribblesdale High.
Ribblesdale High is a route starting right of the arete, climbing past pockets to the break, then moves off a sloping ledge lead hopefully to the top. Given E3 6a. That reminded me that I had pictures of the first ascent by Simon Nevett.
If you click onto the photo to enlarge, the sloping holds right of Simon would be the finish to my project – some hope.
PS. 3rd April 2017.
Probes has just crushed that problem at ?E3 6b Gin Rib.
