2024 Map of Pipes Coulee

About this map

The Sacagawea River winds through this central Montana landscape, defining a terrain shaped by an intricate network of drainage channels. The area is characterized by several named coulees, including Pipes Coulee, Whisker Coulee, and Rasmussen Coulee, which carve through the high plains toward the river and its tributaries. These features reveal a classic regional drainage pattern where ephemeral watercourses like Hay Coulee and Schoneke Coulee dominate the topography. Modern surveying on this sheet highlights the confluence of Little Crooked Creek and Antelope Creek, providing a detailed look at the watershed's structure in Fergus County. The map captures the remote and undisturbed character of this prairie environment, where the land is primarily organized by township and range lines rather than dense human settlement.
