Painting by Henry C. Pitz showing John Wesley Powell and his party going through the Grand Canyon, presumably during the historic 1869 Colorado River expedition. The 1869 expedition gave to Powell and his party the distinction of being the first to travel the entire distance of the Colorado River, a remarkable feat that many had formerly believed impossible.
