2020 Map of Mandaree SE

About this map

Lake Sakakawea dominates the central landscape of this western North Dakota quadrangle, where the Missouri River was transformed into a massive reservoir. The terrain is characterized by high plateaus and dissected breaks, most notably the McGregory Buttes in the northwest. This 2020 record illustrates the modern infrastructure of the Fort Berthold Indian Reservation, where Bureau of Indian Affairs routes like BIA Rd 17 and its spurs, BIA Rd 17 E and BIA Rd 17 W, provide the primary access through the drainage systems of Moccasin Cr. The map highlights the intersection of natural river geography and twentieth-century water management projects that redefined the topography of Dunn County.
