1983 Map of Big Sheep Mountain NW

About this map

Ash Creek flows through this eastern Montana landscape, marking the transition between Mc Cone Co and Prairie Co. The drainage patterns of Pasture Creek and East Duck Creek define the topography, illustrating the watershed structure of the region during the early 1980s. This provisional survey captures the intersection of county lines in a largely open area, where the terrain is dominated by these seasonal watercourses and the survey markers of the period. The map provides a detailed view of the natural hydrology of the area before modern land-use changes, serving as a primary source for understanding the physical geography and administrative boundaries of this portion of the Montana plains.
