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.
Nina Williams climbs "Midnight Lightning", a bouldering problem on the Columbia Boulder in Camp 4 of Yosemite National Park. It has been described as the world's most famous bouldering problem. The first ascent was by Ron Kauk in 1978; the first female ascent was by Lynn Hill in 1998.
