River Master

the long version

In 1869, Civil War veteran and amputee Major John Wesley Powell led an expedition down the uncharted Colorado River through the then-nameless Grand Canyon. This is the story of what started as a geological survey, but ended in danger, chaos, and blood. The men were inexperienced and ill-equipped, and they faced unimaginable peril. Along the way there was death, mutiny, and abject terror, but Powell persevered and produced a masterwork of adventure writing still held in the highest regard by the boatmen who follow his course today.
