2015 Map of Twelvemile Spring

About this map

Twelvemile Spring anchors this remote portion of the Mojave Desert within Inyo County, situated in a low-lying basin between two significant mountain formations. The terrain is defined by the Resting Spring Range to the west and the Nopah Range to the east, creating a corridor known as the Chicago Valley. This landscape reflects the quintessential basin-and-range topography of the eastern California desert, where water sources like the spring were historically vital for transit and survival. Modern access is limited to thoroughfares such as Chicago Valley Rd, which skirts the southern reaches of the valley. The map details the precise township and range lines, such as t23n r7e, marking the cadastral survey of these arid lands. This 2015 edition provides a clear record of the area's natural drainage patterns and the stark geological boundaries of the surrounding desert ranges.
