About this map

Turquoise Mountain and the surrounding Silurian Hills anchor this mid-century survey of the California high desert, where mining activity and transit corridors define the landscape. The map captures a moment of infrastructure development, showing the 4 Lane highway cutting through the terrain alongside specialized landmarks like the Microwave Relay Sta VABM 4511 and the Airway Beacon 4391, which served early aviation and communication networks.

Mineral extraction is the primary human footprint, evidenced by the Turquoise Mining Area and a concentration of named sites including the Great Wanamingo Mine and Wander Mine. Sparse but vital water sources such as Halloran Spring and Francis Spring provide the only natural focal points for small outposts like Cree Camp and Yucca Grove, illustrating the precarious nature of settlement in this arid environment.
