2014 Map of Foundation Spring

About this map

Foundation Spring and the associated Foundation Draw mark a landscape defined by seasonal drainages and remote ranching access along the Custer and Fallon County border. This 2014 survey by the U.S. Geological Survey documents a network of intermittent waterways, including Miles City Cr and Hay Cr, which carve through the high plains. The transition between the two counties is clearly delineated, showing how local jurisdiction follows the section lines of the Public Land Survey System. Transportation in this arid territory is limited to essential connectors like Foundation Rd and Spring Creek Rd, which provide access to the various forks of Locate Cr. The map illustrates the sparse infrastructure typical of this part of eastern Montana, where water sources like the primary spring were essential anchors for early navigation and land use.
