The Clark Fork river dominates the western margin of this area, flowing through a landscape defined by sharp drainage divides and high ridges in the late twentieth century. To the southeast, the terrain rises into the Deerlodge National Forest, where O'Donnell Mountain stands as a prominent landmark. This territory is marked by a complex network of named drainages, including Orofino Creek and Caribou Creek, which feed into the primary river valley. The map documents the boundary between Powell and Deer Lodge counties, cutting across the southern terrain. This 1989 provisional edition, which incorporates field data from as early as 1959, captures a specific moment in Montana's land management history, showing the established section lines and water systems before further modern development. Small settlements and local place names like Racetrack and Dempsey Creek provide anchor points for understanding the early regional transport and ranching patterns of the valley.
