2020 Map of Big Flat West

About this map

Big Flat characterizes this section of north-central Montana, where the plateau landscape is etched by a series of drainage coulees. The boundary between Blaine Co and Phillips Co runs vertically through the center of the sheet, providing a precise reference for local land records and historical property boundaries. The northern reaches are marked by Weigand Reservoir, while the southern terrain transitions into the complex topography of Rocky Coulee and Wolf Coulee. Transportation across this open country is defined by the corridor of Indian Hwy 8 in the west and Mud Creek Rd near the county line. The map illustrates a landscape of high plains punctuated by seasonal watercourses like Chicken Coulee and Corral Coulee, reflecting the ranching and agricultural patterns of the region near the turn of the 21st century.
