2017 Map of Big Coulee

About this map

Big Coulee and Little Box Elder Coulee dominate this landscape within the Agency District of Blaine County, where the high plains are deeply etched by seasonal watercourses. The drainage patterns of Snake Cr and Box Elder Cr reveal a complex network of ridges and ravines typical of North Central Montana. The map documents a sparse but deliberate infrastructure defined by the Reservation Loop and isolated routes like New Hope Rd and Painted Hills Rd. This 2017 survey reflects the enduring spatial organization of the Big Belknap area, where land use is dictated by the dramatic shifts in elevation and the availability of water at features like Threemile Cr.
