John Wesley Powell was a Civil War veteran dedicated to surveying one of the last uncharted territories in the United States: the Grand Canyon. His expedition established the Grand Canyon as a national landmark and -- not without scrutiny -- changed the country's attitude toward the West. American Experience: Lost in the Grand Canyon is an account of one man's journey to discover one of the last Great Unknowns. The beauty of the Grand Canyon was only matched by the dangers it presented to surveyors. Despite the perils, Powell achieved his mission. ~ Brooke Hodess, Rovi
