Big Flat dominates this portion of Phillips County, Montana, characterized by a complex network of coulees and intermittent watercourses. The landscape is defined by the drainage patterns of Chicken Coulee, Tressler Coulee, and Sage Hen Coulee, which carve through the high plains toward larger bodies like Wild Horse Creek. A significant portion of the eastern section is dedicated to the Phillips County Waterfowl Production Area, highlighting the region's importance for migratory bird conservation amidst the arid terrain. Infrastructure is sparse, anchored by the north-south route of Hwy 204 and the evocative Stage Coach Rd near the northern boundary. In the northwest, the Weigand Reservoir near Mud Creek represents a vital water management feature in this agricultural and ranching environment.
