2017 Map of Ninemile Coulee West

About this map

Ninemile Coulee and its neighboring drainage systems define the geography of this North Central Montana landscape. The terrain is characterized by these distinct erosion features, including Roundup Coulee and Sevenmile Coulee, which cut through the high plains. The presence of Tommy Allen Coulee suggests the local history of land ownership or use by early ranching families in Hill County. Human activity in this rural stretch is largely defined by the Public Land Survey System grid, which dictates the layout of local infrastructure like Rd 160 N. This 2017 survey reflects the persistent agricultural and open-range character of the region, where wide-scale ranching operations are organized around the natural contours and occasional water sources provided by these named coulees.
