Broken Horn Creek flows through this high-plains landscape, crossing the boundary line between Johnson Co and Natrona Co. In the late 1960s, this area of Wyoming was defined by its water resources and ranching operations, centered on the Riley Ranch. The drainage systems of the South Fork Powder River and tributaries like Turkey Springs Creek and Lone Bear Creek dictate the topography, supported by man-made infrastructure such as the Neff Reservoir.
