Cactus Valley and the Grand Hogback dominate this 1962 topographical study, where the Colorado River carves through the landscape alongside a dense network of early irrigation systems. Agricultural development is evident in the numerous water projects like the Farmers Irrigation Co Ditch, Lower Cactus Valley Ditch, and the Grass Valley Canal feeding from the Grass Valley Reservoir.
