2017 Map of Horseshoe Lake

About this map

Sumner anchors this high-plains landscape in northern Phillips County, where the terrain is defined by a network of seasonal drainages and local roadways. The map reveals a land sculpted by water, with Cowie Coulee, Gloyn Coulee, Alkali Coulee, and Lambing Coulee carving out the topography between wide sections of prairie. This 2017 survey reflects the remote character of the region, emphasizing how travel follows the contours of the land via routes like Sunnyslope Rd and Turner Cutacross Rd. A central landmark in this otherwise arid environment is Horseshoe Lake, providing a distinctive water feature in an area dominated by coulees. The map is organized by the Public Land Survey System grids for t36n r28e and t35n r28e, illustrating the foundational property lines that still govern this section of the Montana plains.
