2021 Map of Twelvemile Spring

About this map

Twelvemile Spring provides a critical water source in the arid expanse of the Chicago Valley, situated between two prominent mountain chains. This 2021 survey by the U.S. Geological Survey illustrates the stark topography of the eastern Mojave Desert, where the Nopah Range dominates the eastern horizon and the Resting Spring Range rises to the west. The landscape is defined by its isolation and the simple infrastructure of Chicago Valley Rd, which traverses the basin floor. Such maps are essential for understanding the hydrology of the Great Basin, where isolated springs like this one historically dictated travel routes and settlement patterns in an otherwise unforgiving desert environment.
