Description: On May 24, 1869, a one-armed Civil War veteran named John Wesley Powell and a ragtag band of nine mountain men embarked on the last great quest of the American West. No one had ever explored the fabled Grand Canyon. To adventurers of that era it was a region almost as mysterious as Atlantis -- and as perilous.
