2017 Map of Nolan Reservoir

About this map

Nolan Reservoir sits at the center of this high-plains landscape in Blaine County, capturing the seasonal runoff of a drainage network that includes Christenson Br. The map illustrates a remote ranching and grazing territory defined by significant topographic landmarks like Lion Butte and the winding paths of Coal Mine Coulee and Lion Coulee. Human transit through this portion of the Montana prairie is marked by the historical path of the Cow Island Trl, which traverses the terrain alongside local routes like Lloyd Rd and Golden Valley Rd. The presence of Bear Paw Springs and the N Fork Lion Coulee further highlights the critical importance of water sources in this dry, open environment during the early 21st century.
