1982 Map of Longbrake Ranch

About this map

Longbrake Ranch sits at the heart of this Ziebach County landscape, where the drainage patterns of the Cheyenne River Indian Reservation define the terrain. Surveyed in the mid-1970s, the map reveals a remote ranching economy centered on isolated homesteads like Herren Ranch and Irem Ranch. Water management is the primary human imprint on the land, visible through features such as Herren Dam and the complex network of seasonal waterways including Gift Creek and Rattlesnake Creek. The divide between the West Branch Ash Creek and the East Branch Ash Creek illustrates the sprawling nature of these western South Dakota holdings, where vast distances separate the primary residential sites from their vital water sources and grazing lands.
