2020 Map of Lonesome Lake

About this map

Lonesome Lake anchors the southern reaches of this landscape, where the flat plains of Northern Montana are punctuated by significant drainage features. The boundary between Hill Co and Chouteau Co bisects the quadrangle, marking a transition in local jurisdiction across this sparsely populated terrain. The geography is defined by seasonal water movements and erosional patterns, most notably Twelvemile Coulee and Barneys Coulee, which carve through the high prairie. A network of rural section-line roads, including Box Elder Rd and Ihmsen Well Rd, provides access to these remote lands. This survey illustrates the modern configuration of Montana's agricultural and ranching interior, where the availability of water at the lake and along the coulees remains the primary driver of human movement and land use.
