John Muir,
The Grand Cañon of the Colorado
“ Others seem to grow from mere points, and fly high above the cañon, yet following its course for a long time, noiseless, as if hunting, then suddenly darting lightning at unseen marks, and hurrying on. Or they loiter here and there as if idle, like laborers out of work, waiting to be hired.Half a dozen or more showers may oftentimes be seen falling at once, while far the greater part of the sky is in sunshine, and not a raindrop comes nigh one. These thunder-showers from as many separate clouds, looking like wisps of long hair, may vary greatly in effects. ”
