2024 Map of Four Horns Lake

About this map

Four Horns Lake serves as the central hydrological feature of this northern Montana landscape, where the waters of the Four Horns Outlet Canal and Blacktail Creek define the local drainage patterns. The terrain is marked by a series of significant coulees, including Jackson Coulee, Big Plum Coulee, and Tail Feather Coulee, which illustrate the complex erosional history of the plains. Situated along the boundary of Glacier and Pondera Counties, this area reveals a landscape primarily dedicated to water management and primitive transit. Connectivity is provided by established routes like Four Horns Lake Trl and the Rocky Ridge Trl, which follow the natural contours of the Rocky Ridge upland. This survey provides a precise record of these landforms and water systems as they existed in the early twenty-first century.
