2018 Map of West of Vopoki Ridge

About this map

Yuma and the vast Yuma Desert dominate this southern Arizona survey, which tracks the international boundary where the United States and Mexico meet. The landscape is defined by its arid, open stretches and the critical transit corridor of Border Rd, which runs along the southern edge of the quadrangle. This 2018 edition reveals the modern surveying of the Sonoran landscape, where the shifting sands and gradual elevation changes are meticulously recorded through contour lines. The map provides a clear view of the geopolitical boundary and the isolated infrastructure necessary to maintain this remote borderland, offering researchers a precise look at the township and range divisions that structure this desert territory.
