But That Is Impossible.

The human mind cannot realize the effects of vastness and power this Canyon scenery produces, except when one stands below the cliffs and looks up.

And where the opportunity is given of looking both up to towering walls, and down over beetling precipices, the effect is enhanced.

The Tonto Sandstones. Below the plateau, slight slopes lead the eye to the last of the stratified rocks, the Tonto sandstones of the Cambrian period. These are readily distinguished, mainly by their deep buff color and the fact that generally they are found resting on the archaean or unstratified rocks, locally though incorrectly termed the granite, which makes the Inner Gorge through which the river runs. This "granite" is in the main a blackish gneiss.

The Algonkian Strata. Though the Tonto sandstones usually occupy the location named, there is a deviation from this in the presence of some remnants of strata of the Algonkian period, directly opposite El Tovar. This deviation is discussed in the chapter "How the Canyon was Formed." These remarkable rocks occur to the left (west) of Bright Angel Creek, and lie immediately above the gneiss. Their brilliant red reveals them, and they can be followed up under the base of the Cheops and to a small wash to the left of Osiris. At the mouth of Bright Angel, they rest upon the archaean, with the Tonto sandstones above them, but just in front of the Battleship a break in the gneiss occurs, and on the portion nearest us the Algonkian strata totally disappear, for the Tonto strata rest directly upon the gneiss.
