1968 Map of Tattnall

About this map

Burlington Northern rails track the winding course of Whitewater Creek in this remote section of Phillips County, Montana. The settlement at Tattnall serves as a small anchor in a landscape defined by an intricate network of drainage channels, including Clark Coulee, Coop Coulee, and Bell Coulee. This 1968 survey was conducted as part of the Department of the Interior program for the development of the Missouri River Basin, reflecting the federal interest in mapping water resources and land use in the high plains. Small-scale water management is evident through features like Austin Dam and Hanson Dam, which likely provided vital stock water for ranching operations. The terrain is marked by numerous springs and intermittent flows, such as Lush Coulee and Gregory Coulee, illustrating the sparse but essential hydrology of north-central Montana.
