1971 Map of Griffin Coulee

About this map

Griffin Coulee and the surrounding drainage basins of Rosebud County define this landscape as it appeared in the early 1970s. The terrain is deeply incised by watercourses such as Armells Creek and its major tributary, West Fork Armells Creek, reflecting the complex erosion patterns typical of the Montana plains. Settlement is sparse, represented by the Gillin Ranch in the southern portion of the quadrangle. Industrial development is evident through the presence of a significant Pipeline corridor and the Burlington Northern railroad line, which follows the valley of Armells Creek. The map also identifies a Drill Hole south of West Sheep Creek, signaling subsurface exploration during this era. Other notable water features include the forks of West Cromo Creek and East Cromo Creek, providing a detailed look at the local geography used by ranchers and land managers.
