2020 Map of Horseshoe Lake

About this map

Sumner sits at the heart of this North Central Montana landscape, an area defined by its deep coulees and isolated prairie water features. The terrain is marked by seasonal drainage patterns including Alkali Coulee, Cowie Coulee, and Lambing Coulee, which carve through the high plains of Phillips County. The eponymous Horseshoe Lake remains a focal point in the northeast, set against a grid of sectional lines and rural routes like Sunnyslope Rd and Turner Cutacross Rd. This modern survey illustrates the persistent agricultural and ranching layout of the region, where the vast open spaces between Gloyn Coulee and the surrounding townships reflect the sparse settlement patterns typical of the Big Sky Country.
