2024 Map of Sourdough School

About this map

The Cayuse Hills rise above a complex network of drainages in this ranching-dominated landscape of Sweet Grass County. The map captures the significant hydrological infrastructure of the High Plains, including the Baggs Ditch irrigation system and the winding paths of Sweet Grass Creek and its major tributaries. This 2024 survey documents the enduring pastoral character of the region, where the land is carved by the Dry Fork Sweet Grass Creek and East Fork Sweet Grass Creek. Transportation across this expansive terrain relies on established routes such as Rapelje Rd, Tin Can Hill Rd, and Sourdough Rd, which connect the scattered homesteads and ranches. The cartography provides a clear view of the Public Land Survey System grids, specifically marking sections within t3n r16e and t2n r17e.
