About this map

The Missouri River carves through the northern reaches of this landscape, marking the boundary where Roosevelt and Richland counties meet. This modern survey illustrates a rugged topography defined by deeply incised drainages and named coulees that feed into larger waterways. Significant terrain features like Mortarstone Bluff and the prominent Haystack Butte rise above the surrounding prairie, providing clear landmarks in a region largely defined by its natural hydrology and relief.

Evidence of early rural infrastructure remains visible, such as Fisher Cem located near the headwaters of West Charlie Creek. The map documents a network of local transit including Co RD 316 and several Bureau of Indian Affairs routes like Bia Rte 1. The drainage patterns, including Coalmine Coulee and Simons Coulee, reveal the complex erosion of the Missouri River breaks, offering a contemporary look at the preservation of traditional land use and place names in eastern Montana.
