Larb Hills rise above a landscape defined by an intricate network of drainage coulees along the border of Phillips and Valley counties. This modern topographic record details the high point at Spencer Point and the complex erosional features that segment the terrain, including Dead Horse Coulee, McNab Coulee, and Hadley Coulee. The map illustrates the rural infrastructure of this ranching country, where unpaved routes like Beaver Creek Rd and the Harb Trl provide access through the breaks. Waterways such as Larb Creek and Third Creek snake through the townships, while landmarks like Pack Rat Coulee and Lost Coulee emphasize the area's remote, named geography. This survey provides a precise accounting of land divisions and topographical relief in a largely undeveloped stretch of Northern Montana.
