2020 Map of Blacktail Lake

About this map

Blacktail Lake serves as a central landmark in this portion of Williams County, where the high plains terrain is carved by the Little Muddy River and its various tributaries. The settlement of Blacktail sits on the western shore of the lake, while the small community of Marmon is located further southeast. This 2020 survey reveals a landscape largely defined by its rural road network and water drainage patterns, including Heidemann Coulee and Blacktail Cr. For genealogists and local historians, the map provides precise locations for the Bethel Lutheran Cem and Faith Cem, which serve as lasting markers of the area's pioneer heritage. The Public Land Survey System grid remains the primary organizing force for the region's development, with township lines like t158n r101w delineating the agricultural and residential tracts.
