2020 Map of Rudie Coulee

About this map

Rudie Coulee and the surrounding drainage network of Rosebud County characterize this high plains landscape. The terrain is defined by its seasonal watercourses, including the Little Porcupine Cr and its tributaries, the E Fork Little Porcupine Cr and Ryans Fork. The presence of Badland Coulee and Wildcat Coulee suggests the type of eroded, broken ground common in this part of Montana, where the natural topography dictates the few established routes. Transport through this open country is limited to gravel and improved paths such as Little Porcupine Creek Rd, Rd 202, and Rd 124. This survey illustrates the relationship between the dry coulees and the intermittent creek beds that have carved the land over centuries, providing a detailed record of land divisions and topographical elevations in an area defined by its geographic isolation.
