Canyons of the Colorado

"Canyons of the Colorado" by John Wesley Powell is an account first published in 1875 and revised in 1895. It chronicles the first recorded expedition by white men through the Grand Canyon in 1869, a three-month journey down the Green and Colorado rivers through unexplored southwestern canyon country. Powell and his crew faced near-drownings, lost supplies, and departures of several members, yet produced the first detailed descriptions and maps of this vast, unknown landscape.
