About this map

Sweet Grass County ranching lands and coulees define this mid-century landscape, mapped as part of the Department of the Interior program for the development of the Missouri River Basin. The topography is characterized by a complex network of draws and creeks, including Tangen Draw in the northwest and Nash Gulch cutting across the central hills. Human activity is marked by scattered infrastructure like the Wulff Ranch and a trio of named thoroughfares: Sourdough Road, Gibson Road, and Howie Road.

To the north, Glasston Lake and the prominent VABM 4912 Glass serve as key local landmarks. Drainage patterns are essential to the character of this terrain, with Sweet Grass Creek flowing along the eastern boundary, fed by tributaries such as Ryan Creek and Hamilton Creek. The map provides a clear look at the rural survey and land-use patterns of the Montana plains before later modern developments altered the local roadway networks.
