1973 Map of Larslan NW

About this map

Avondale stands as the primary settlement marker within this High Plains landscape, situated along the northern reaches of a drainage system that includes Hell Creek. The geography is defined by the East Fork Snow Coulee, which winds southward across the terrain toward the Fort Peck Indian Reservation Boundary. This 1970s survey captures the precise demarcation where public lands meet reservation territory, a critical boundary for understanding land use and historical tenure in this part of Montana. The sparse distribution of man-made features reflects a ranching and agricultural economy, where small clusters of buildings and survey markers provide the only navigational anchors in an expanse dominated by seasonal coulees and wide prairie draws.
