The Grand Canyon was discovered in 1540 by El Tovar, one of the captains of Cardenas, in charge of one of the expeditions of the Spanish explorer, Diaz, who was hunting for seven fabled cities of vast wealth. "They reached the banks of a river which seemed to be more than three or four leagues above the stream that flowed between them." It was seen in 1776 by a Spanish priest who sought a crossing and found one at a point far above the canyon; this still bears the name Vado de los Padres.
By 1840 it was probably known to the trappers who overran the country. In 1850 Lieutenant Whipple, surveying for a Pacific route, explored the Black Canyon and ascended the Grand Canyon to Diamond Creek.
In 1857 Lieutenant Ives, sent by the War Department to test the navigability of the Colorado, ascended as far as the Virgin River in a steamboat which he had shipped in pieces from Philadelphia. From there he entered the Grand Canyon afoot, climbed to the rim, and, making a detour, encountered the river again higher up. In 1867 James White was picked up below the Virgin River lashed to floating logs. He said that his hunting-party near the head of the Colorado River, attacked by Indians, had escaped upon a raft. This presently broke up in the rapids and his companions were lost. He lashed himself to the wreckage and was washed through the Grand Canyon.
About this time Major John Wesley Powell, a school-teacher who had lost an arm in the Civil War, determined to explore the great canyons of the Green and Colorado Rivers. Besides the immense benefit to science, the expedition promised a great adventure. Many lives had been lost in these canyons and wonderful were the tales told concerning them. Indians reported that huge cataracts were hidden in their depths and that in one place the river swept through an underground passage.
Nevertheless, with the financial backing of the State institutions of Illinois and the Chicago Academy of Science, Powell got together a party of ten men with four open boats, provisions for ten months, and all necessary scientific instruments. He started above the canyons of the Green River on May 24, 1869.
There are many canyons on the Green and Colorado Rivers. They vary in length from eight to a hundred and fifty miles, with walls successively rising from thirteen hundred to thirty-five hundred feet in height. The climax of all, the Grand Canyon, is two hundred and seventeen miles long, with walls six thousand feet in height.
