1951 Map of Topock

About this map

The Colorado River carves a dramatic path through the Mohave Mountains on this 1951 survey, creating the sharp bends and rocky passages of Mohave Canyon. This corridor serves as a vital transportation artery, featuring the Atchison Topeka and Santa Fe railroad and the historic National Old Trails Road crossing near Topock. The mapping reflects the mid-century landscape of the lower Colorado, including the Havasu Lake National Wildlife Refuge and the Fort Mohave Indian Res. Small-scale mining operations like the Jackpot Mine and Boulder Mine are scattered throughout the arid uplands, while the river's edge shows early aviation and water management infrastructure, including the Topock Landing Field and a Gaging Sta. Landforms such as Cathedral Rock and Castle Rock define the shoreline of Havasu Lake.
