The international border with Canada defines the southern edge of this Montana landscape, where the prairie begins its northward stretch into Saskatchewan. The terrain is marked by a network of intermittent wetlands and drainage patterns typical of the Northern Great Plains. Lyons Cr winds through the eastern portion of the map, serving as a primary hydrological feature in an area dominated by subtle topographic shifts and seasonal water storage. The 2017 survey by the U.S. Geological Survey details a sparsely developed region where the land use is dictated by the natural flow of the creek and the vast, open stretches of the borderlands.
