Water sometimes does queer things, but it has never been known to reverse nature. By a fundamental law of hydrostatics water always seeks its level and flows in the direction of least resistance. If water ever made the Grand Canon it had to climb a hill and cut its way through the backbone of the Buckskin mountains, which are not a range of peaks but a broad plateau of solid rock. Into this rock the canon is sunk more than a mile deep, from six to eighteen miles wide and over two hundred miles long.
In order to make the theory of water erosion tenable it is assumed that the Colorado river started in its incipiency like any other river. After a time the river bed began to rise and was gradually pushed up more and more by some unknown subterranean force as the water cut deeper and deeper into the rock until the Grand Canon was formed.
Captain Hance has a theory that the canon originated in an underground stream which tunneled until it cut its way through to the surface. As improbable as is this theory it is as plausible as the erosion theory, but both theories appear to be equally absurd.
At some remote period of time the entire southwest was rent and torn by an awful cataclysm which caused numerous fissures and seams to appear all over the country. The force that did the work had its origin in the earth and acted by producing lateral displacement rather than direct upheaval. Whenever that event occurred the fracture which marks the course of the Grand Canon was made and, breaking through the enclosing wall of the Great Basin, set free the waters of an inland sea. What the seismic force began the flood of liberated water helped to finish, and there was born the greatest natural wonder of the known world.
There are canons all over Arizona and the southwest that resemble the Grand Canon, except that they were made on a smaller scale.
Many of them are perfectly dry and apparently never contained any running water. They are all so much alike that they were evidently made at the same time and by the same cause. Walnut Canon and Canon Diablo are familiar examples of canon formation.
The rocks in the canons do not stand on end, but lie in horizontal strata and show but little dip anywhere. Indeed, the rocks lie so plumb in many places that they resemble the most perfect masonry.
The rim rock of the Mogollon Mesa is of the same character as the walls of the Grand Canon and is an important part of the canon system. It is almost a perpendicular cliff from one to three thousand feet high which extends from east to west across central Arizona and divides the great northern plateau from the southern valleys. It is one side of an immense vault or canon wall whose mate has been lost or dropped completely out of sight.
In many of the canons where water flows continuously, effects are produced that are exactly the opposite of those ascribed to water erosion. Instead of the running water cutting deeper into the earth it has partly filled the canon with alluvium, thereby demonstrating nature's universal leveling process. Even the floods of water which pour through them during every rainy season with an almost irresistible force carry in more soil than they wash out and every freshet only adds new soil to the old deposits. If these canons were all originally made by water erosion as is claimed, why does not the water continue to act in the same manner now but, instead, completely reverses itself as above stated? There can be but one of two conclusions, either that nature has changed or that scientists are mistaken.
The Aravaipa in southern Arizona is an interesting canon and is typical of its kind. Its upper half is shallow and bounded by low rolling foothills, but in the middle it suddenly deepens and narrows into a box canon, which has high perpendicular walls of solid rock like the Grand Canon. It is a long, narrow valley sunk deep into the earth and has great fertility and much wild beauty. It measures from a few feet to a mile in width and drains a large scope of rough country. The surface water which filters through from above reappears in numerous springs of clear cold water in the bottom of the canon. In the moist earth and under the shade of forest trees grow a variety of rare flowers, ferns and mosses.
Where the canon begins to box a large spring of pure cold water issues from the sand in the bottom of a wash which is the source of the Aravaipa creek. It flows through many miles of rich alluvial land and empties into the San Predo river. The valley was settled many years ago by men who were attracted to the spot by its rare beauty, fertility of soil and an abundance of wood and water.
The land is moist and covered by a heavy growth of forest trees, which will average over one hundred feet high. The trees are as large and the foliage as dense as in any eastern forest. Being sunk deep in the earth the narrow valley at the bottom of the canon can only be seen from above. When viewed from some favorable point it has the appearance of a long green ribbon stretched loosely over a brown landscape. The sight of it is a pleasant surprise to the weary wayfarer who, after traveling over many miles of dreary desert road, finds himself suddenly ushered into such pleasant scenes.
The canons of Arizona are unrivaled for grandeur, sublimity and beauty, and will attract an ever increasing number of admirers.
