2017 Map of Day School SW

About this map

The Marias River carves a winding path through this high plains landscape in Chouteau County, creating a deeply eroded corridor defined by extensive coulee systems. To the north, Sheep Coulee branches away from the river valley, while further south, Lone Tree Coulee and Slide Out Coulee mark the dramatic breaks in the prairie topography. This 2017 survey illustrates the sparse, rural character of the region, where infrastructure is limited to occasional routes like Stevens Rd. The map also captures the drainage patterns of smaller tributaries such as Chip Cr, showing how water has historically shaped the agricultural and ranching potential of these northern Montana grasslands.
