About this map

Nez Perce National Historical Park anchors the southern portion of this landscape in Blaine County, marking a site of significant cultural and historical weight in the Big Hole Basin. The terrain is defined by a series of branching drainages and coulees that cut through the high plains, including Sixmile Coulee, Willman Coulee, and Lonetree Coulee. These features illustrate the erosion patterns of the northern Montana prairie, where water is the primary architect of the land. A network of rural routes such as Cleveland Rd, Lloyd Rd, and the curiously named Oil Field Loop suggest a history of resource exploration and agricultural access. Along the eastern edge, Box Elder Cr and Olson Road Coulee drain toward the Bear Paw Mountains, while Snake Cr meanders across the central sections, creating a complex system of seasonal waterways.
