I climbed as I had never climbed before, and though the day was hot I reached the Saddle in an hour, and, without a moment’s pause, turned toward Great Mountain and commenced the long ascent of its rocky slope. In fifty-five minutes more I reached the summit and had ascended 3275 feet above Lake Louise. The air was still clear and offered every promise of successful photographs, even as I was unstrapping my camera and preparing to set it up for work. Suddenly, the wind shifted once more to the south and brought back great banks of smoke, which came rolling over the snowy crest of Mount Lefroy like fog from the sea. In five minutes all was lost. Mount Temple appeared like a great, shadowy ghost, in the bluish haze, and the sun shone with a pale coppery light. Such are the trials and tribulations of the climber in the Canadian Rockies.

One day at the end of August, H. and I ascended this mountain with our surveying instruments. The barometer had been steadily falling for several days, and already there were cumulus clouds driving up from the southwest in long furrows of lighter and darker vapors, which obscured the entire sky. A few drops of rain on the summit compelled me to work rapidly, but, as yet, there was no warning of what was in store.

After all the principal points were located we packed up our instruments and commenced a rapid descent to the Saddle. The slope is of scree and loose material, which permits a rapid descent at a full run, so that one may gain the Saddle in about fifteen minutes. Arriving there I paused to get a drink at a small stream under some great boulders, fed by a wasting snow-bank. H. had gone off toward the other side of the pass to get his rifle, which he had left on the way up.

Suddenly I heard a rushing sound, and, looking up, saw a cloud of dust on the mountain side and the trees swaying violently in a strong wind. A mass of curling vapor formed rapidly against the cliffs of Great Mountain, and a dull moaning sound, as of violent wind, seemed to fill the air. The sky rapidly darkened and black clouds formed overhead, while below them the thin wisps of scud rushed along and seemed white and pale by contrast.

I was no sooner up on my feet than the approaching blast was upon me, and with such unexpected force did it come that I was laid low at the first impulse. My hat went sailing off into space and was never seen more. The first shock over, I gained my feet again and started to find H. The air changed in temperature with phenomenal rapidity, and from being warm and muggy, in the space of about five minutes it grew exceedingly cold, and threatened snow and hail.

Though everything betokened an immediate storm and a probable drenching for us, I had time to notice a magnificent sight on Mount Temple. As yet there were no clouds on the summit, but, as I looked, my attention was called to a little fleck of vapor resting against the precipitous side of the mountain, half-way between summit and base. So suddenly had it appeared that I could not tell whether it had grown before my eyes or was there before. From this small spot the vapors grew and extended rapidly in both directions, till a long, flat cloud stretched out more than a mile, when I last saw it. The vapors seemed to form out of the very air where a moment before all had been perfectly clear.

Realizing that the sooner we started the better chance we should have of escape, we flew rather than ran down the trail, and were only overtaken by the storm as we approached the lake. The temperature had dropped so rapidly that a cold rain and damp snow were falling when we reached the lake. The boat had drifted from its moorings, and was caught on a sunken log some distance from the shore. I waded out on a sunken log, where I expected at any moment to slip from the slimy surface and take an involuntary bath in the lake. The boat was regained by the time H. had arrived a few minutes later and we reached the chalet thoroughly drenched.

Such sudden storms in the Canadian Rockies are rather rare, and are almost always indicated in advance by a falling barometer and lowering sky. I have never at any other time observed such a sudden fall in temperature, nor seen the clouds form instantaneously far down on the mountain side as they had done in this storm. The sudden rush of wind, the curling vapors, and flying scud afforded a magnificent spectacle on the Saddle, and one that was well worth the drenching we suffered in penalty.
