About this map

Larb Hills and the surrounding high plains of north-central Montana dominate this landscape as it was documented in the early 1970s. The region is defined by a dense network of intermittent drainage channels and deep-cut ravines, notably Black Coulee, White Horse Coulee, and Lone Tree Coulee. These topographic features emphasize the arid, erosive character of the terrain where the Phillips Co and Valley Co border runs north to south through the eastern half of the map.

A notable geological depression known as The Sag lies in the southern portion of the sheet, providing a distinct landform contrast to the rising hills. Water resources, critical in this high prairie environment, are represented by small, named reservoirs and creek beds like Beartracks Reservoir and the winding Larb Creek. The map documents a land primarily used for ranching and resource extraction, indicated by the network of fence lines and a solitary Gravel Pit.
