2014 Map of Sourdough School

About this map

Sourdough Cr and Sixshooter Cr trace the drainage patterns of this high plains region in south-central Montana. The landscape is defined by its watercourses, including Cottonwood Cr and Carson Cr, which have historically dictated the placement of ranching outposts and grazing lands. This 2014 survey records the traditional township and range divisions of the American West, capturing a quiet section of Sweet Grass County where topography and hydrology remain the primary drivers of land use. The map serves as a detailed record of the rural infrastructure and natural drainage as it existed in the early 21st century.
