2020 Map of Miller Springs

About this map

Miller Springs and Johnson Springs define the water-dependent landscape of this Valley County region, where intricate coulees and man-made impoundments serve as vital resources. The terrain is deeply incised by a network of drainage features, most notably Rock Creek Canyon and Eagles Nest Coulee, which highlight the erosive character of the local geography. Numerous small reservoirs, such as Mary Black Reservoir, Emory Reservoir, and Book Reservoir, illustrate the historical and ongoing management of surface water in this arid stretch of Montana. Transport across the area is guided by primitive routes like Rock Creek Rd and Sleaker Rd, connecting isolated landmarks like the Landre Hills to the wider county. This survey documents the specific placement of these catchments and springs, essential for understanding the ranching and agricultural history of the High Plains.
