2024 Map of Rudie Coulee

About this map

Little Porcupine Creek and its primary tributaries dominate this portion of the Rosebud County landscape, illustrating a drainage system defined by intermittent watercourses and topographic breaks. The hydrology of the area is characterized by several named coulees, including Rudie Coulee in the northwest and Badland Coulee to the west, which channel seasonal runoff into the larger creek valley. The terrain is marked by the distinct paths of East Fork Little Porcupine Creek and Wildcat Coulee, which converge as they move toward the southern reaches of the quadrangle. Transport across this sparsely populated ranching country is facilitated by a network of rural routes, notably Little Porcupine Creek Rd and several numbered access roads like Rd 202. This contemporary survey highlights the enduring isolation of the Big Sky country, where geography is still largely defined by the township and range system and the natural flow of the local forks.
