1984 Map of Chapman NW

About this map

Woody Island Coulee winds through the southern portion of this high-plains landscape, serving as the primary drainage feature for this international borderland. Published in 1984, this survey captures the precise intersection of the Canada-United States boundary and the Montana-Saskatchewan provincial line. The terrain is defined by the administrative meeting of the Blaine Co and Phillips Co line, where the landscape is characterized by intricate contouring that details the glacial potholes and depressions common to this prairie environment. The map provides a meticulous record of the northern Montana range just prior to the mid-1980s, documenting few human structures but clearly marking the established property and political boundaries that organized this remote stretch of the American West.
