1966 Map of Alamo Dam

About this map

The Alamo Dam and the forming Alamo Lake dominate the northern landscape of this 1960s Arizona survey, marking a significant hydrological shift at the confluence of the Bill Williams River and its desert tributaries. The map documents the terrain just as the dam's reservoir began to reshape the local geography, inundating areas along the Mohave and Yuma county lines. To the south, the vast expanse of Butler Valley is framed by the Buckskin Mountains and the Harcuvar Mountains, revealing a remote ranching and mining landscape reached only by unimproved roads and a Jeep Trail.
