About this map

The Plomosa Mountains dominate this 1990 provisional study, revealing a landscape defined by intensive mineral exploration and geological investigation. The terrain is marked by an exceptional concentration of mining activity, from the Mudersbach Mine and Southern Cross Mine to the numerous Prospects and Adits that dot the slopes. These features, alongside specialized labels like the Tough Nut Shafts and various Miner Adit Shafts, offer a detailed look at the resource extraction history within this arid corner of Arizona.

Beyond the industrial markings, the map captures the transition from the high elevations of Ibex Peak and Haystack Peak down toward the open Ranegras Plain. This area is crisscrossed by 4wd tracks that provided the only access for surveyors and miners. The presence of several Guzzler points indicates the vital, managed water sources necessary for desert wildlife and perhaps the occasional traveler or prospector in this remote environment.
