Although W. S. Green had made an attempt in 1888, it was not until two years later that the giant of the Selkirks, Mount Sir Donald, was conquered. In July, 1890, Carl Sulzer and Emil Huber, of the Swiss Alpine Club, set out one morning about 4 o'clock from their camp at timber line, determined to find a way to the summit of the magnificent peak that shot up into the sky from their very feet. They had already studied the mountain from several points, and had selected a route that looked promising. Crossing a small glacier, they turned up a couloir or gully terminating in a cave, above which the cliffs rose almost perpendicularly. The last part of the couloir became so narrow that the climbers had to force their way up by propping their bodies in the angle against the rocks on either side. After a short rest, they started climbing up to the rocks of the southern ridge. It was stiff work in places even for such experienced mountaineers, but finally they reached the main crest and "gazed beyond the undulating tops of the foothills, upon the far-stretched row of blue peaks of the Rocky Mountains." Following the arête, or steep ridge of the mountain, and overcoming more than one difficulty as they went, they finally stood upon the summit, 10,800 feet above the sea. From this isolated point they had a wonderful view of the Selkirks, with the main range of the Rockies in the distance. "The finest view presented itself in the southwest and south. Above the undulations of the Asulkan and Illecillewaet glaciers and opposite a deep valley, the fine group of Mount Dawson arose with its two corner-pillars, Mount Donkin and Mount Fox. But the most beautiful mountain of all appeared above the opening between Mount Dawson and Mount Donkin. It was Mount Purity, very properly so called, a snow mountain of the finest order." Building a cairn to commemorate the first ascent of Sir Donald, and burying in it a bottle containing a record of the climb, ending with the jubilant words, "Three cheers for Switzerland," they retraced their way down the mountain, and were enthusiastically received at Glacier House, news of the first big climb in the Selkirks being immediately telegraphed east and west. Toward the end of the same month, Herr Huber, accompanied by Messrs. Topham and Forster, of the English Alpine Club, made the first ascent of Mount Purity, which had been named by Topham. They camped on the western slopes of the mountain, and set out for the summit about sunrise the following morning. The climb was a comparatively easy one to such seasoned mountaineers, and two hours' work brought the party to the summit. Meanwhile Herr Sulzer was attacking another virgin peak, which he had named Swiss Peak. He had but one companion, with little or no experience in mountain-climbing, so that the attempt was a somewhat daring one.
