About this map

The Missouri River forms a major geographic boundary on this Montana prairie landscape, separating Roosevelt and McCone counties. Along the northern bank, the Burlington Northern railroad tracks parallel the water, passing near Chelsea Creek and the Fort Peck Indian Reservation Boundary. This area demonstrates the intersection of indigenous lands and industrial infrastructure during the early 1970s, with several pipelines and an elevated line segment cutting across the northern township blocks.

To the south of the river, the terrain rises into the high country around Spread Eagle, where the land is marked by small-scale resource extraction including several labeled mines and a Drill Hole. Local connectivity is defined by Nickwall Road, which winds through the coulees near Nickwall Creek and the Nickwall Dam, serving a region of scattered springs and rugged drainage patterns typical of this portion of the Great Plains.
