1970 Map of Halliday NW

About this map

The Fort Berthold Indian Reservation Boundary cuts across this prairie landscape in Dunn County, marking the edge of Tribal lands as they meet the rising waters of the Missouri River Basin. Much of the northern terrain is defined by the expansive Lake Sakakawea, where the irregular shoreline creates deep inlets like Wolf Chief Bay. This 1970 field-checked survey illustrates a transitional period for the region, documenting areas subject to controlled inundation as the reservoir system matured. Away from the water, the topography is carved by drainage systems including Hans Creek and North Creek. The map also traces a significant Pipeline traversing the southwestern sections, reflecting the energy infrastructure underlying the rural North Dakota plains.
