1982 Map of Irish Creek NW

About this map

Standing Rock Indian Reservation lands dominate the northern landscape of this region, meeting the Cheyenne River Indian Reservation Boundary in a sparse, open expanse of the Dakotas. The terrain is defined by the winding course of Irish Creek, which threads through the southern half of the map. This 1982 provisional survey reflects the rural character of the border between Corson Co and Ziebach Co, showing a land primarily organized by township and section lines rather than dense settlement. The map captures the isolation of the northern plains, where natural drainage patterns like those of Irish Creek provided the essential framework for land division and early ranching boundaries in this part of South Dakota.
