Today is the 121st anniversary of driving the last spike on the Canadian Pacific Railway creating a transcontinental system across Canada. That's Donald Alexander Smith, a CP director, wielding the spike hammer, with William Cornelius Van Horne, CP's general manager, standing behind and to the left of him (with the black beard and moustache). The last spike was driven at Craigellachie, British Columbia, on November 7, 1885. (photo courtesy of the National Library and Archives of Canada)
