About this map

Turquoise Mountain and the Silurian Hills dominate this Mojave landscape, revealing an era of intense mineral prospecting in the mid-1950s. The map documents numerous mining operations, ranging from the Turquoise Mining Area to the Great Wanamingo Mine and Telegraph Mine. These extraction sites are linked by a network of unimproved dirt roads and the primary artery of 91, which cuts through the center of the sheet past Halloran Spring.

Water sources are critical landmarks in this arid environment, with Francis Spring, Bull Spr, and Henry Spring providing essential points of reference. The infrastructure of mid-century communication and aviation is also evident through the Microwave Relay Sta and an Airway Beacon. Small settlements like Cree Camp and Yucca Grove serve as isolated outposts amidst prominent terrain features such as Squaw Mtn and the distinct volcanic formation of Lava at the southern edge.
