An even more productive partnership with the less well-known Jimmy Marshall was to result in a string of landmark first ascents. In one winter week on Ben Nevis in February 1960 they were to transform the shape of Scottish winter mountaineering. Using rudimentary ice-climbing gear, Smith and Marshall led six difficult and committing routes at the cutting edge of what was then possible. They also repeated Point Five Gully in seven hours, a route that had only been climbed once before the previous year by a team led by the English climber Ian Clough which took more than 40 hours over six days. Smith and Marshall were to interrupt their week with a single rest day involving descent to Fort William, a pub crawl and temporary arrest by the local constabulary over an incident with some dominoes. This brief respite was not to slow their pace, indeed their final day was to be one of the finest of their climbing careers with the ascent of Orion Direct, a climb alpine in atmosphere and so advanced that Scottish winter mountaineering had to wait a decade before changes in technique and equipment permitted a repeat. The events of this winter week with Marshall are repeated and celebrated in the film, ‘The Pinnacle’ (2010).
