The romance of the Colorado River : the story of its discovery in 1540, with an account of the later explorations, and with special reference to the voyages of Powell through the line of the great canyons
A 1903 New York and London history of the Colorado River by Frederick Dellenbaugh, a travel-explorer writer, published by G.P. Putnam's Sons for general readers interested in western exploration. Its photographs show canyon country: a figure gazing over a sandy valley, a winding river far below, a narrow rock passage with a pool, and a sweeping view of eroded Arizona cliffs, giving a designer studies of deep rock strata and dramatic scale.
