This reaction is apparent in the writings of those who have visited it; no other spectacle in America has inspired so large a literature. Joaquin Miller found it fearful, full of glory, full of God. Charles Dudley Warner pronounced it by far the most sublime of earthly spectacles. William Winter saw it a pageant of ghastly desolation. Hamlin Garland found its lines chaotic and disturbing but its combinations of color and shadow beautiful. Upon John Muir it bestowed a new sense of earth's beauty.

Marius R. Campbell, whose geological researches have familiarized him with Nature's scenic gamut, told me that his first day on the rim left him emotionally cold; it was not until he had lived with the spectacle that realization slowly dawned. I think this is the experience of very many, a fact which renders still more tragic a prevailing public assumption that the Grand Canyon is a one-day stop in a transcontinental journey.

It is not surprising that wonder is deeply stirred by its vastness, its complexity, and the realization of Nature's titanic labor in its making. It is far from strange that extreme elation sometimes follows upon a revelation so stupendous and different. That beauty so extraordinary should momentarily free emotion from control is natural enough. But why the expressions of repulsion not infrequently encountered upon the printed pages of the past? I have personally inquired of many of our own day without finding one, even among the most sensitive, whom it repelled. Perhaps a clew is discovered in the introductory paragraphs of an inspired word-picture which the late Clarence E. Dutton hid in a technical geological paper of 1880. "The lover of nature," he wrote, "whose perceptions have been trained in the Alps, in Italy, Germany, or New England, in the Appalachians or Cordilleras, in Scotland or Colorado, would enter this strange region with a shock and dwell there with a sense of oppression, and perhaps with horror. Whatsoever things he had learned to regard as beautiful and noble he would seldom or never see, and whatsoever he might see would appear to him as anything but beautiful or noble. Whatsoever might be bold or striking would seem at first only grotesque. The colors would be the very ones he had learned to shun as tawdry or bizarre. The tones and shades, modest and tender, subdued yet rich, in which his fancy had always taken special delight, would be the ones which are conspicuously absent."

I suspect that this repulsion, this horror, as several have called it, was born of the conventions of an earlier generation which bound conceptions of taste and beauty, as of art, dress, religion, and human relations generally, in shackles which do not exist in these days of individualism and broad horizons. To-day we see the Grand Canyon with profound astonishment but without prejudice. Its amazing size, its bewildering configuration, its unprecedented combinations of color affect the freed and elated consciousness of our times as another and perhaps an ultimate revelation in nature of law, order, and beauty.

In these pages I shall make no attempt to describe the Grand Canyon. Nature has written her own description, graving it with a pen of water in rocks which run the series of the eternal ages. Her story can be read only in the original; translations are futile. Here I shall try only to help a little in the reading.

The Grand Canyon was cut by one of the great rivers of the continent, the Colorado, which enters Arizona from the north and swings sharply west; thence it turns south to form most of Arizona's western boundary, and a few miles over the Mexican border empties into the head of the Gulf of California. It drains three hundred thousand square miles of Arizona, Utah, Wyoming, and Colorado. It is formed in Utah by the confluence of the Green and the Grand Rivers. Including the greater of these, the Green River, it makes a stream fifteen hundred miles in length which collects the waters of the divide south and east of the Great Basin and of many ranges of the Rocky Mountain system. The Grand River, for its contribution, collects the drainage of the Rockies' mighty western slopes in Colorado.

The lower reaches of these great tributaries and practically all of the Colorado River itself flow through more than five hundred miles of canyons which they were obliged to dig through the slowly upheaving sandstone plateaus in order to maintain their access to the sea. Succeeding canyons bear names designating their scenic or geologic character. Progressively southward they score deeper into the strata of the earth's crust until, as they approach their climax, they break through the bottom of the Paleozoic limestone deep into the heart of the Archean gneiss. This limestone trench is known as the Marble Canyon, the Archean trench as the Granite Gorge. The lower part of the Marble Canyon and all the Granite Gorge, together with their broad, vividly colored and fantastically carved upper canyon ten miles across from rim to rim, a mile high from water to rim-level, the climax of the world of canyons and the most gorgeous spectacle on earth, is the Grand Canyon of the Colorado. It lies east and west in the northern part of the State.
