Clark Fork and the Thompson River meet in a landscape defined by sharp drainage systems and the vast boundaries of the Lolo National Forest. This 1999 revision of earlier 1960s topography reveals a late 20th-century view of the river-corridor settlements, including Weeksville and the riverside cluster known as The Pines. The map records the precise alignment of the Fifth Standard Parallel North, illustrating the intersection of the Public Land Survey System with the complex hydrology of Montana's mountain valleys. Small-scale industrial activity is noted near the river via the Substation and a Gravel Pit, while numerous named drainages like Bill Buffalo Creek, Lynch Creek, and Smiley Creek cut through the forest, detailing the intricate watershed of the region.
