1956 Map of Blackwater Lake

About this map

Ft Berthold Indian Reservation Boundary divides this central North Dakota landscape, marking a transition across the prairie of McLean County. The map documents a rural school system in decline by the mid-1950s, noted by the prevalence of defunct institutions like School No 3, School No 4, and Ziegler Sch. In contrast, the White Shield Sch stands as an active center near the reservation line. Small local hubs are anchored by the Immanuel Ch and Roseglen Cem, while the hamlet of Glennon sits near the head of Coulee. The terrain is defined by low-lying wetlands and seasonal water bodies such as Brumwell Slough and Minehan Slough, which feed into Blackwater Lake and the West Branch of Douglas Creek.
