2021 Map of Bear Hills

About this map

The arid expanse of Ranegras Plain stretches across this western Arizona landscape, framed by the sharp rises of the Plomosa Mountains and the distinct volcanic forms of the Bear Hills. This region, documented by the U.S. Geological Survey in 2021, centers on the small roadside settlements of Brenda and Pioneer, which serve as vital hubs in an otherwise sparse desert environment. The mapping reveals a transition from traditional desert travel routes to modern infrastructure, where historical traces like Stage Coach Rd and names like Ramsey Mine Rd hint at the area's mining and transit history. The local road network, including Black Rock Tank Rd and Deadwood Ave, provides a clear view of how development has clustered around the highway corridor while maintaining its connection to the surrounding wilderness and the large-scale township grids of the Public Land Survey System.
