Last weekend I was able to shoot some video of Erik Eisele and Scott Bubnis climbing on Cathedral Ledge. Their route of choice was Diagonal- a long dike leading up an endless slab. The first pitch was thin snow and ice leading up to a ledge with a few small trees for a belay. It then followed a the dike to an icicle oozing from a chimney. Their climbing was impressive. Climbing an exposed slab in January with crampons is something that I'd gladly avoid.
This clip is just a preview of more video to come.
