1964 Map of Day School SW

About this map

The winding Marias River carves a deep valley through this Chouteau County landscape as it appeared in the mid-1960s. This survey, conducted as part of the Missouri River Basin development program, shows a region defined by its drainage systems and agricultural infrastructure. Numerous coulees, such as Sheep Coulee, Lone Tree Coulee, and Slide Out Coulee, slice through the surrounding plains toward the riverbed. Human activity is focused on ranching and storage, evidenced by the presence of a Corral and clusters of Storage Bins scattered across the high ground. The map detail is particularly useful for locating small water sources like a Spring tucked into a side coulee, and tracing the intermittent flow of Chip Creek. The lack of formal townsites highlights the isolated, pastoral nature of the river breaks during this era of Montana's history.
