The Musselshell River defines the landscape of this central Montana region, winding past the county seat of Roundup and into the coal-rich terrain of the Bull Mountains. In the late 1970s, the industrial footprint of the Bull Mountain coal field remains prominent, with mining infrastructure like Republic Mine No 2 and the Keene Mine marking the hills south of the river. The small mining settlements of Klein, Gibbtown, and Farreltown are clustered along the drainage of Halfbreed Creek, illustrating the localized worker communities that once thrived near the shaft entrances. Within the town of Roundup, essential civic landmarks are clearly documented, including the Courthouse, Post Office, and Roundup Memorial Hospital. North of the river, the terrain shifts toward more open ranching and agricultural use, characterized by long drainages like Alkali Creek and Willow Creek, while early mining operations like the Square Deal Mine and Niles Mine are found further west.
