1986 Map of Lake Mason SE

About this map

Devils Basin dominates this 1986 survey of the Central Montana landscape within Musselshell County. The terrain is defined by the winding course of Willow Creek, which carves through the basin alongside several smaller unnamed drainages and coulees. A notable modern addition to this rural landscape is a pipeline that traverses the southeastern portion of the quadrangle, cutting a linear path across the natural contours. Produced as a provisional edition, this map captures the region's ranching and resource-based character during the mid-1980s, documenting a sparsely settled area where the physical geography remains the primary feature of interest for local historians and land use researchers.
