The Sacagawea River carves a winding path through this portion of Petroleum County, defining the drainage patterns of a landscape marked by intermittent coulees and seasonal waterways. Tributaries like Hay Coulee and Carpenter Coulee feed into the river from the north, while the southern terrain is characterized by the expansive basins of Alkali Creek and Drag Creek. Human presence is sparse in this stretch of central Montana, anchored primarily by the passage of Crooked Creek Rd, which provides the main terrestrial connection across the varied elevations. This 2011 survey documents the natural hydrography of the region in high detail, showing the intricate network of small streams and runoff channels that shape the Missouri River watershed in this isolated area.
