One is tempted to repeat the story of the first successful ascent of Mount Deltaform, described by Wilcox as the "most difficult mountain yet ascended in the Canadian Rockies;" and of Wilcox's own climb up Mount Temple, but both are readily accessible in the _Rockies of Canada_. Some idea of the magnitude of the task of scaling Deltaform may be got from the fact that an unusually strong climbing party consisting of Professor H. C. Parker, Dr. A. Eggers, and the Swiss guides Hans and Christian Kaufmann, were nearly twenty-two hours in conquering the peak, "after a reconnaissance and repulse two days before." This sketch of mountain-climbing in the main range of the Canadian Rockies, designed merely to give as far as possible in the words of the actors, some idea of the experiences incident to this king of sports, may close with an account of the first ascent of Crows Nest Mountain, one of the most difficult climbs in the Southern Canadian Rockies. P. D. McTavish tells the story in the _Canadian Alpine Journal_, 1907. In August, 1905, Mr. McTavish, with three friends, reached the base of the mountain and after several attempts which ended in quite impossible precipices, found a great crevice leading up about 400 feet and "resembling the space left in a whole cheese when a thin wedge-shaped piece has been removed." After resting for a time, they climbed up to a dome of rock which had obstructed their view. "With some difficulty we surmounted this, and found ourselves at the base of a beautifully straight, but very perpendicular, chimney, about six feet in width and two hundred feet high. This offered possibilities, so we immediately proceeded to climb to the top. Arriving there, a short shaly slope led to a similar chimney, up which we climbed. We now found ourselves at the top of the first circular band which begirts the mountain, and felt that victory was within our grasp. "For some time we encountered a series of steep, rocky slopes and perpendicular faces, which led to a long slope of about one thousand feet, after which the climbing again became fairly difficult, but for only a short time, as we had reached the final dome, and at 12.15 o'clock we stood upon the summit." The entire climb had occupied about four hours. [Illustration: THE ASSAULT. _Byron Harmon_] [Illustration: VICTORY AT LAST. _Byron Harmon_] [Illustration: THE MONARCH OF THE ROCKIES.
