About this map

The Colorado River carves a striking path through the desert on this 1970s topographic survey, marking the jagged boundary between Arizona and California. The settlement of Topock serves as a critical infrastructure hub where the Atchison Topeka and Santa Fe railroad and highways cross the water at the Red Rock Bridge. To the south, the river enters the dramatic Topock Gorge, passing through The Needles and the Havasu National Wildlife Refuge.

Mineral extraction and water management are evident across the landscape, from the Jackpot Mine and Gold Dome Mine in the Mohave Mountains to the various gaging stations along the riverbanks. The map also delineates the southern portion of the Ft Mojave Indian Res and complex wetlands like Topock Marsh near Catfish Paradise, illustrating the varied uses of the river corridor before the modern era of desert expansion.
