2024 Map of Sand Arroyo

About this map

Fort Peck Lake and the southeastern reaches of the Charles M Russell National Wildlife Refuge define this section of the Missouri River breaks in McCone County. The terrain is characterized by a network of drainage features and named high points such as Westland Hill and Goat Mtn, indicating the complex topography where the West Fork and South Fork Sand Arroyo converge near the Sand Arroyo settlement. The presence of Nelson Airport and local arteries like N Rock Creek Rd and Shade Creek Rd provide insight into the rural transportation and ranching access required in this sparsely populated region. For those tracing land use, the map clearly delineates the CMR NWR boundary alongside family-named landmarks like Andrews Coulee and Bergland Coulee, which often reflect the early homesteading history of the Missouri River badlands.
