2014 Map of Tweed Mine

About this map

Chocolate Mountains terrain dominates this corner of the Sonoran Desert, where the arid landscape is defined by the drainage networks of Mohave Wash and Gould Wash. The map centers on the Tweed Mine, a site that anchors the local history of mineral exploration in this desolate reach of the Arizona borderlands. To the north, the elevation subsides into the La Posa Plain, while distinctive geological formations are noted within the interior ridges, including two separate features labeled as Natural Arch. Navigated primarily by the desert track of Cibola Rd, the area straddles the boundary between La Paz and Yuma counties, preserving a record of this remote mining and wilderness region as it existed in the early 21st century.
