The wind slackened and snow began to fall just as we were leaving the smooth plateau for the broken part of the divide. The next mile of way was badly cut to pieces with deep gorges from both sides of the ridge. The inner ends of several of these broke through the centre of the ridge and extended beyond the ends of the gorges from the opposite side. This made the course a series of sharp, short zigzags. We went forward in the flying snow. I could scarcely see, but felt that I could keep the way on the broken ridge between the numerous rents and cañons. On snowy, icy ledges the wind took reckless liberties. I wanted to stop but dared not, for the cold was intense enough to freeze one in a few minutes. Fearing that a snow-whirl might separate us, I fastened one end of my light, strong rope to Scotch's collar and the other end to my belt. This proved to be fortunate for both, for while we were crossing an icy, though moderate, slope, a gust of wind swept me off my feet and started us sliding. It was not steep, but was so slippery I could not stop, nor see where the slope ended, and I grabbed in vain at the few icy projections. Scotch also lost his footing and was sliding and rolling about, and the wind was hurrying us along, when I threw myself flat and dug at the ice with fingers and toes. In the midst of my unsuccessful efforts we were brought to a sudden stop by the rope between us catching over a small rock-point that was thrust up through the ice. Around this in every direction was smooth, sloping ice; this, with the high wind, made me wonder for a moment how we were to get safely off the slope. The belt axe proved the means, for with it I reached out as far as I could and chopped a hole in the ice, while with the other hand I clung to the rock-point. Then, returning the axe to my belt, I caught hold in the chopped place and pulled myself forward, repeating this until on safe footing. In oncoming darkness and whirling snow I had safely rounded the ends of two gorges and was hurrying forward over a comparatively level stretch, with the wind at my back boosting along. Scotch was running by my side and evidently was trusting me to guard against all dangers. This I tried to do. Suddenly, however, there came a fierce dash of wind and whirl of snow that hid everything. Instantly I flung myself flat, trying to stop quickly. Just as I did this I caught the strange, weird sound made by high wind as it sweeps across a cañon, and at once realized that we were close to a storm-hidden gorge. I stopped against a rock, while Scotch slid in and was hauled back with the rope. The gorge had been encountered between two out-thrusting side gorges, and between these in the darkness I had a cold time feeling my way out. At last I came to a cairn of stones which I recognized. The way had been missed by only a few yards, but this miss had been nearly fatal.
