Planning to go down the west side, I crossed the table-like top, found, after many trials, a break in the enormous snow-cornice, and started down the steep slope. It was a dangerous descent, for the rock was steep and smooth as a wall, and was overladen with snow which might slip at any moment. I descended slowly and with great caution, so as not to start the snow, as well as to guard against slipping and losing control of myself. It was like descending a mile of steep, snow-covered barn roof,--nothing to lay hold of and omnipresent opportunity for slipping. A short distance below the summit the clouds again were around me and I could see only a short distance. I went sideways, with my long skees, which I had now regained, at right angles to the slope; slowly, a few inches at a time, I eased myself down, planting one skee firmly before I moved the other. [Illustration: A SNOW-SLIDE REGION Near Telluride, Colorado] At last I reached a point where the wall was sufficiently tilted to be called a slope, though it was still too steep for safe coasting. The clouds lifted and were floating away, while the sun made the mountains of snow still whiter. I paused to look back and up, to where the wall ended in the blue sky, and could not understand how I had come safely down, even with the long tacks I had made, which showed clearly up to the snow-corniced, mist-shrouded crags at the summit. I had come down the side of a precipitous amphitheatre which rose a thousand feet or more above me. A short distance down the mountain, the slopes of this amphitheatre concentrated in a narrow gulch that extended two miles or more. Altogether it was like being in an enormous frying-pan lying face up. I was in the pan just above the place where the gulch handle joined. It was a bad place to get out of, and thousands of tons of snow clinging to the steeps and sagging from corniced crests ready to slip, plunge down, and sweep the very spot on which I stood, showed most impressively that it was a perilous place to be in. As I stood gazing upward and wondering how the snow ever could have held while I came down this cloud over the crest in an inverted cascade. All this showed for a few seconds until the snowy spray began to separate and vanish in the air. The snow-cloud settled downward and began to roll forward. Then monsters of massed snow appeared beneath the front of the cloud and plunged down the slopes. Wildly, grandly they dragged the entire snow-cloud in their wake. At the same instant the remainder of the snow-cornice was suddenly enveloped in another explosive snow-cloud effect. A general slide had started. I whirled to escape, pointed my skees down the slope,--and went. In less than half a minute a tremendous snow avalanche, one hundred or perhaps two hundred feet deep and five or six hundred feet long, thundered over the spot where I had stood.
