2021 Map of Vopoki Ridge

About this map

Vopoki Ridge dominates the high ground of this southwestern Arizona landscape, serving as a prominent north-south landform between the Gila Mountains and the lower Butler Mountains to the southeast. The 2021 survey illustrates a region defined by its arid topography, where the steep relief of Spook Canyon drops away into the expansive, flat reach of Davis Plain. The map provides a precise view of the Public Land Survey System grid across Yuma County, marking the township and range boundaries of t11s r20w and t12s r20w. While modern infrastructure is sparse, the map documents the essential desert tracks and drainage patterns that have historically dictated movement through these mountain passes and plains.
