Mount McKinley's "Smoke." Every so often Mount McKinley, in Alaska's national park of that name. is accused of smoking. Observers declare that the old mountain has turned volcanic, and is eluptins fire and brimstone, not to mention clouds of smoke. Such tales, however, are erroneous. McKinley is always accused of doing its smoking in the winter, during especially cold weather. This would seem t o be the sensible time t o smoke, if smoke the mountain must. Old-timers in the north, however, explain the "smoking" phenomenon as anything hut "hot." They say that during periods of very high winds and low temperature, dry, loose snow, crystallized by the extreme cold, is picked up by the wind, and if the mountain is encountered in its course the snow is hurled up and over its crest in such a manner that, under certain conditions of light, the flying mass takes on the color of dark slate as it streams off over the top into space. From a distance this strongly resembles smoke. Mount McKinley has been known t o throw off a "smoke-screen" of this type estimated t o he from twenty t o fifty miles long.-Science Service
