About this map

Brown Spring and the surrounding high plains of central Montana define this transition zone between the Fergus and Petroleum county lines. The landscape is deeply etched by watercourses including Dovetail Cr and Blood Cr, which have carved significant features such as Connoly Coulee and Carter Coulee into the prairie. These drainage patterns dictate the placement of local thoroughfares like Dovetail Rd and Valentine RD, which serve the remote ranching and grazing lands of this region.

Dog Butte and Dunn Ridge stand as prominent landmarks in a terrain characterized by subtle elevation changes and wide-open grazing allotments. This 2017 survey reflects a largely unchanged rural environment, where modern infrastructure is limited to primitive routes like 79 Trl. The map provides a clear view of the complex legal and geographic boundaries where these two counties intersect in the Missouri River breaks area.
