1970 Map of Lost Bridge

About this map

The Little Missouri River carves a winding path through the Badlands of western North Dakota, marking a landscape of significant elevation changes and seasonal watercourses. At the time of this 1970 field check, the river transitions into the rising waters of Lake Sakakawea Elevation 1838, an artificial reservoir created by the Garrison Dam. This inundation boundary is a defining feature of the area, as the water reaches up into the coulees and draws of the surrounding terrain. To the south, the massive landform of North Killdeer Mountain stands as a prominent landmark overlooking the drainage basins of Corral Creek. The northeastern portion of the map is defined by the Fort Berthold Indian Reservation Boundary, while the Lost Bridge Public Use Area provides a specific point of access to this remote riverine environment before the further development of the region's infrastructure.
