1990 Map of Hummingbird Spring

About this map

Moon Anchor Mine and the US Mine anchor the industrial character of this desert landscape, where mining activity is recorded through dozens of prospect pits and mine shafts scattered throughout the territory. The terrain is defined by prominent elevations such as Sugarloaf Mountain, Big Horn Peak, and Black Butte, while human infrastructure is limited to rugged tracks like Old Camp Road and Woodchopper Road. Resource management in this arid environment is evident through labels like Dead Horse Tank, Wildcat Well, and the namesake Hummingbird Spring. This 1990 provisional update, based on earlier surveys and field checks from 1986, captures a specific era of mineral exploration and land use in western Maricopa County, showing the network of washes like Coyote Wash and Dead Horse Wash that dictate the natural flow of the land.
