Hiram Martin Chittenden, The Yellowstone National Park: Historical and Descriptive
“ The pure water of its snow-fed streams, the exhilarating atmosphere, the bracing effect of altitude, the wholesome fatigue of daily rambles over the rough, mountainous country, the fragrant odor of the pine boughs which every-where pervades the atmosphere, and, above all, the beautiful and varied scenery, which exalts the mind and diverts the attention from cares that are too often the real cause of physical ills—these are the true virtues of the Yellowstone Park as a health resort. ”
