1983 Map of Sullivan Coulee

About this map

The Redwater River and its meandering tributaries carve through the boundary of Richland and McCone counties in this 1983 provisional survey. The landscape is defined by an intricate network of drainage systems, including the prominent Sullivan Coulee and Davis Coulee, which shape the local topography. This era of mapping captured the rural character of the Montana plains before significant modern alterations, showing the relationship between the major waterway and its smaller offshoots like East Redwater Creek and Milne Coulee. The presence of Muskrat Creek in the eastern portion of the quadrangle highlights the complex hydrology of this drainage basin, which has long influenced land use and cattle ranching patterns in this part of eastern Montana.
