La Posa Plain dominates the landscape of this 1927 survey, showing the arid expanse of Yuma County before modern development. The northern edge of the map is defined by the critical infrastructure of the era, where the Atchison Topeka and Santa Fe railway runs parallel to Bouse Wash. The small settlement of Linskey serves as a lone station along this rail line, adjacent to the ephemeral watercourse. To the east, the sharp rise of the Plomosa Mountains creates a dramatic boundary, including the prominent landmark of Four Peaks. The transition from the flat, open desert to these high ridges is marked by a series of alluvial fans and isolated water sources like Tenmile Well. In the south, the early automotive era is represented by the Sunkist Trail, a primary desert route cutting through the basin towards the mountain passes.
