1983 Map of Hay Creek

About this map

The Fort Peck Indian Reservation landscape is defined by the intermittent drainages of the Missouri River plateau as documented in this 1983 provisional survey. Hay Creek runs through the central and southern portions of the quadrangle, serving as a primary drainage corridor for the high prairie. The map details a network of deeply etched coulees typical of the northern Great Plains, including Swank Coulee and Kirns Coulee. These features represent the essential topography for local land use, showing how water movement has shaped the benchlands and provided natural pathways through the Roosevelt County interior. Compiled from 1975 aerial photography, the sheet records the remote character of this reservation land during a period of minimal structural development, focusing instead on the complex relief and elevation changes of the high plains.
