2020 Map of Lost Bridge

About this map

The Little Missouri River meanders across the northern portion of this Dunn County landscape, carving a deep valley that stands in sharp contrast to the surrounding high plains. Near the eastern edge, the crossing at Lost Bridge serves as a critical point of orientation in an otherwise sparsely settled region of the Missouri Plateau. The terrain is defined by dramatic elevation changes, notably at the southern margin where the prominence of North Killdeer Mtn rises above the drainage basins.
