Frederick Dellenbaugh was still a teenager when he joined John Wesley Powell’s second expedition as artist and assistant topographer in 1871. He tells the story of the boats’ descent from Green River, Wyoming, through the canyons of the Green and Colorado to the Grand Canyon, with the surveying, the rapids, the portages and the months of overland exploring.
