About this map

Lonesome Lake anchors the southern portion of this high-plains landscape, where the geography is defined by seasonal water drainage and the subtle shifts in the North Central Montana prairie. The map depicts the transition between Hill and Chouteau counties, a boundary that runs through a region marked by extensive coulees like Twelvemile Coulee and Barneys Coulee. These features represent the natural erosion patterns typical of this semi-arid environment.

Local industry is represented by several Gravel Pits and a solitary Gravel Pit located just north of the lake. These sites, along with a network of unimproved roads and sectional fencing, point to a landscape primarily used for ranching and resource extraction in the late 1960s. The absence of major settlements highlights the isolated, agricultural nature of this part of the Big Sandy region during this era.
