Nathaniel Pitt Langford, The Discovery of Yellowstone Park
“ The two grand falls of the Yellowstone form a fitting completion to this stupendous climax of wonders. They impart life, power, light and majesty to an assemblage of elements, which without them would be the most gloomy and horrible solitude in nature. Their eternal anthem, echoing from cañon, mountain, rock and woodland, thrills you with delight, and you gaze with rapture at the iris-crowned curtains of fleecy foam as they plunge into gulfs enveloped in mist and spray. ”
