“ The river, then, passes through what are called "The Gates of the Rocky Mountains." The river appears to have torn for itself a passage through the mountain. For the distance of six miles, perpendicular cliffs of dark colored rock, rise twelve hundred feet above the stream which washes their base! The chasm is not more than three hundred feet wide, and the deep, foaming waters rush through, with the speed of a race-horse. In no situation in life, does man so keenly feel his own imbecility and nothingness, as when viewing such terrible results of a war between the elements of nature. ”
