The Clark Fork river serves as a primary corridor through this Montana landscape, where the valley floor transitions into the steep slopes of the Lolo National Forest. This 1963 survey captures a period of active transportation and water management, illustrated by the presence of both the Northern Pacific and the Chicago Milwaukee St Paul and Pacific railroads. Irrigation systems like the Frenchtown Irrigation District Ditch and the Grass Valley French Ditch reveal the agricultural infrastructure required to support settlements such as Schilling and Primrose. The map documents local landmarks like the Grass Valley Sch and the Sherman Gulch Beacon, while industrial activities are marked by the Schilling Gravel Pit. Steep ravines like Cyr Gulch and Martin Gulch define the western terrain, contrasting with the open expanse of Big Flat.
