In 2009 the University of Utah Press and the Utah State Historical Society co-published three volumes of long out-of-print journals, letters, and other documents from John Wesley Powell's expeditions down the Colorado River. This is the fourth and final volume. This beautifully illustrated book features Hillers's photographs—long regarded as a remarkable and unique record of the Colorado River and the Grand Canyon.
