About this map

The Ft Berthold Indian Reservation Boundary divides this prairie landscape, where the northern half is characterized by the expansive township of Roseglen. The map documents a period of significant consolidation or shift in rural education, evidenced by the numerous decommissioned sites like School No 3 (Abandoned) and Ziegler Sch (Abandoned). In contrast, the White Shield Sch stands as an active center of the community south of the boundary line.

Water management and natural drainage are central to the terrain, with Blackwater Lake and the Minehan Slough situated centrally. The hydrology of the area is further defined by the West Branch feeding into Douglas Creek in the southeast. Cultural markers like the Roseglen Cem and Immanuel Ch provide fixed points for genealogists tracing family histories in this part of McLean County during the mid-1950s.
