Further wonders are revealed every few thousand feet.  At the mouth of the next creek the coloring is different.  The strata dips visibly, and the marble, which has hitherto been exposed to view, is now beneath the surface.  The sandstone forms the river boundary, and rises at a sharp angle from the water’s edge.  The river itself is narrow in consequence, but the great valley is even wider at the top.  The walls vary in height from 2,000 to 8,000 feet, and in rainy seasons the water rushes down the side in great profusion.  Thousands of little rivulets join the main stream, and add greatly to the volume of water.  Sometimes the river will rise four or five feet in a single night, upsetting all calculation, and making navigation risky in the extreme.  When, by chance, the sun is able to penetrate into the depths of this canon, the kaleidoscopic effects are exquisite, and cause the most indifferent to pause and wonder.

The discovery of an extinct volcano explains a great deal of the wonders of the great canon.  The volcano is examined by thousands of tourists, this being one of the spots to reach which scientists are willing to incur countless hardships and risks.  No one can tell when the volcano was active, but from the nature of the crater it is perfectly clear that at one time it belched forth volumes of lava, which had a marked effect on the formation of the rock and the lay of the land of the surrounding country.  Past the volcano, for many miles, the bright colors already referred to are supplanted by more sombre hues.  Occasionally there is a little scarlet, and, as a rule, the sandstone is covered with the mysterious substance brought out of the bowels of the earth by the now silent, but once magnificently awful, mountains.

The exploring party to which we have referred, went through 600 miles of canons, and found that no two miles were really alike.  Finally, after three months of hardship, they emerged into an open country, and became almost frantic with joy.  Never did country seem so beautiful, or verdure so attractive, and the panorama of beauty which was presented to their view caused them to shout with delight, and to offer up cries of thankfulness for their ultimate deliverance from a series of hardships and dangers which at one time seemed almost insurmountable.

The region also abounds with archaeological curiosities and remarkable hieroglyphics.  Many of these are found in close proximity to the Grand Canon of the Colorado, and on the cliffs in which the far-famed cliff dwellers of old took up their abode.  Hieroglyphics, marked upon rocks or other lasting substances, have been used by nearly all ancient races to perpetuate the history of certain events among them.  Especially true is this of the ancient people who lived in Arizona.  The remarkable picture rocks and boulders, with strange symbols upon them, left by the prehistoric races of Arizona, have been the cause of much discussion among
