This guide to mountaineering in Canada was one of several issued by CPR in the years 1904, 1905, 1906 and 1909, all with the same title but with different covers. This version contains photographic illustrations using the “Lumiere Process of Direct Colour Photography”. The booklet quotes from various authorities, including Edward Whymper, who had visited the Rockies in 1900 at the invitation of CPR.
