2015 Map of Fiftymile Flat

About this map

S Fork Powder River carves a winding path through the heart of this Natrona County landscape, defining the topography of the central high plains. The area is characterized by a series of named draws and water catchments that highlight the importance of water management in this arid environment, including Blue Hill Reservoir, Jack Reservoir, and Three T Reservoir. Distinctive landforms such as Broken Horn and The Gap serve as significant local landmarks, while the broad expanse of Fiftymile Flat occupies the central northern reaches. Infrastructure is sparse, anchored primarily by rural routes like Harlan Ranch Rd and various county roads that navigate the complex system of coulees and draws, including Stone and Timber Draw and Austin Draw.
