About this map

Suphellen Reservoir sits at the northern edge of this high plains landscape in Toole County, where the topography is defined by a complex network of seasonal drainage channels. The area is marked by numerous coulees, including Fifteenmile Coulee, Taylor Coulee, and the eponymous Antelope Coulee, which weave through the section lines of the Public Land Survey System. These landforms reveal the erosional patterns characteristic of the Montana plains, providing vital drainage for the region's agricultural and ranching operations.

Transportation through this rural expanse relies on a grid of maintained routes such as the Oilmont Hwy and Woldtvedt Rd, which connect remote homesteads and sections. The presence of named features like Picadilly Coulee and Johannson Coulee suggests a history of local land naming tied to early settlers. This 2014 survey by the U.S. Geological Survey details the intersection of modern road infrastructure with the natural relief of the northern Montana landscape.
