2011 Map of Nolan Reservoir

About this map

Lion Butte rises above a landscape defined by deep coulees and seasonal drainages in this Blaine County region. The small settlement of Leroy anchors the southern portion of the map, situated near the headwaters of North Fork Lion Coulee. Water management is central to the area's geography, evidenced by the centrally located Nolan Reservoir and the presence of Bear Paw Springs. The map documents historic routes through the northern Montana plains, including the Cow Island Trl, a path with deep ties to regional freighting and movement. The branching waters of Christenson Branch and the appropriately named Coal Mine Coulee suggest a landscape where natural resources and ranching infrastructure intersect along established corridors like Golden Valley Rd.
