1984 Map of Down Reservoir NE

About this map

The high plains of Northern Montana are defined by the convergence of the Blaine Co and Phillips Co lines in this 1980s-era topographic study. The landscape is characterized by a network of drainage channels including Little Jewel Coulee and Black Coulee, which snake across the plateau. The terrain is largely dominated by the natural hydrology of the region, where seasonal water flow has carved distinct paths toward Reservoir Coulee in the east. This map captures the area as it was recorded during a 1979 field check, reflecting a sparse, rural environment where the primary features are defined by the relief of the coulees rather than human infrastructure or settlement. It provides a technical record of the land surface before contemporary digital mapping, emphasizing the subtle contours and boundaries of these two adjacent counties.
