1983 Map of Sadie Coulee

About this map

Sadie Coulee and its intricate network of drainage channels dominate this McCone County landscape, revealing a highly eroded terrain characteristic of eastern Montana. The map highlights the reliance on water management in this arid ranching country, evidenced by the presence of Gass Reservoir and scattered wells. While the area lacks dense settlements, the naming conventions of features like Young Rosie Coulee, Dead Man Coulee, and John Coulee suggest a history of early cattle grazing and homesteading where local landmarks were identified by family names or notable incidents. Small traces of community life appear in the form of a cemetery, providing a point of interest for genealogists tracking early inhabitants of the region. The drainage patterns of Prairie Elk Creek and Porcupine Creek further illustrate the topographic complexity of this territory during the late 1970s and early 1980s.
