"The Grand Canyon...is the land of music. The river thunders in perpetual roar, swelling in floods of music when the storm Gods play upon the rocks, and fading away in soft and low murmurs when the infinite blue of heaven is unveiled. With the melody of the great tide rising and falling, swelling and vanishing forever, other melodies are heard in the gorges of the lateral canyons, while the waters plunge in the rapids among the rocks or leap in great cataracts. Thus the Grand Canyon is a land of song. Mountains of music swell in the rivers, hills of music billow in the creeks and meadows of music murmur in the rills that ripples over the rocks."
~ John Wesley Powell
