1984 Map of Flat Coulee

About this map

Larb Creek flows through this expansive stretch of northern Montana, defining a landscape of deep drainage systems along the boundary of Phillips and Valley counties. Surveyed in the late 1970s, this area is characterized by its complex network of coulees, including Coon Coulee, Lost Coulee, and the prominent Flat Coulee that names the quadrangle. The terrain is marked by distinctive elevations such as Dead Mans Hill, which overlooks a series of branching waterways like Blanche Coulee and Whites Coulee. Human presence is spare, primarily traced through the winding path of Larb Road. The map provides a detailed view of the regional hydrology, showing how the South Fork Box Elder Coulee and Box Elder Coulee navigate the breaks of this high plains environment.
