About this map

The arid landscape of Sentinel Plain and the winding course of the Gila R define this 1980s topographic record of Maricopa County. This provisional survey captures a stretch of desert terrain punctuated by distinct geological markers and early resource extraction attempts. Historical activity is signaled by various Prospects scattered across the northwestern quadrant, indicating small-scale mining interests typical of the region's development history.

Prominent landforms include the notable Sentinel Peak in the southeast and the sheltered topography of Wild Horse Canyon. The inclusion of Oatman Flat in the northeast provides a specific reference point for local history enthusiasts tracking the route of the Gila River trail. This sheet focuses heavily on elevation and drainage patterns, documenting the environment as it existed before further modern expansion in the Arizona desert.
