2021 Map of Sentinel Peak

About this map

Sentinel Peak rises as the primary landmark in this corner of Maricopa County, anchoring a landscape shaped by vast township and range divisions. The terrain is traversed by several significant corridors including Oatman Rd, S Oatman Rd, and Painted Rock Rd, which reflect the historic transit patterns across the desert. These routes, alongside S Agua Caliente Rd, suggest the long-standing importance of these desert passages for regional connectivity. The map primarily documents the geometric precision of the Public Land Survey System, illustrating how boundaries like t5s r9w and t6s r9w organized the territory into a structured grid. This 2021 study by the U.S. Geological Survey provides a detailed record of the physical relief and existing road network, serving as a modern reference for the enduring geography of the Arizona desert.
