About this map

The Sweet Grass Hills dominate the northwestern corner of this landscape, where the terrain breaks into a series of deeply etched drainages. The map reveals a ranching country defined by its water sources, from the Morris Reservoir and Chicago Lake to the scattered springs like Alkali Spring and 35N03E20AACC01 Spring. This high plains environment is dissected by numerous named coulees, including La Planté Coulee and Grandma Coulee, suggesting a long history of local naming conventions for the many folds in the land.

Infrastructure is sparse, consisting primarily of gravel tracks such as Strawberry Rd and Furnell Ranch Rd, which connect the isolated homesteads and grazing lands across the Toole Co Liberty Co boundary. The prevalence of family-named features like Jack McDonald Coulee and Johnson Coulee points to the specific lineages that have managed these Montana rangelands, while prominent landmarks like Grassy Butte and Mid Butte serve as critical navigation points in the open country.
