[VIDEO] Nina Williams and Helen Sinclair climbing „The Rostrum“ (5.11c) in Yosemite Valley, CA

Nina Williams teams up with Y.O.S.A.R. member Helen Sinclair to take on the Rostrum in Yosemite as one of her first true Multi-Pitch Trad climbs. Every pitch is high quality and would be sought after individual classics were they at any crag, but stacked on top of each other they create a superb and memorable challenge.
