2014 Map of North Chinook Reservoir NE OE N

About this map

The high plains of northern Blaine Co meet the international boundary on this 2014 survey. This portion of north-central Montana is defined by a sparse, aquatic landscape where the drainage of Lyons Cr winds through open country toward the Canada / United States of America border. The map illustrates a remote prairie environment, punctuated by numerous small depressions and intermittent water bodies that characterize the glaciated terrain of the northern Great Plains. While settlements are absent from this specific quadrangle, the precise mapping of the border line and local drainages provides a detailed look at the geography of the Milk River basin region just before the mid-2010s.
