2014 Map of Big Flat West

About this map

Big Flat characterizes the high, open terrain of this region along the border of Blaine and Phillips Counties. The landscape is defined by a series of significant drainage features, including Corral Coulee and Lone Tree Coulee to the north, which give way to the deeper incisions of Wolf Coulee and Chicken Coulee further south. These landforms trace the natural flow of water across the prairie toward the more substantial Rocky Coulee in the southeast corner. Human presence is marked by the long stretch of Mud Creek Rd and Bia-8, which provide the primary access through this rural expanse. In the northeast, Weigand Reservoir serves as a critical water resource for this arid environment, illustrating the engineering required to support land use in this part of the state.
