1973 Map of Line Coulee

About this map

The Fort Peck Indian Reservation Boundary cuts across the southern reach of this Daniels County landscape, separating the reservation lands from the surrounding prairie. This 1973 survey reveals a rugged, drainage-carved terrain dominated by the winding path of Big Line Coulee and its smaller namesake, Line Coulee. The map shows a region shaped by its water sources, where sparse landmarks like Springs and a lone Well provide the essential points of reference for ranching and land management in this remote corner of northeastern Montana. The intricate contour work illustrates the deep erosion patterns of the coulees as they cut through the high plains, offering a precise look at the land's character before modern agricultural or infrastructure changes altered the rural fabric of the area.
