About this map

The Flathead Indian Reservation encompasses this 1960s landscape, defined by the convergence of the Middle Fork Jocko River and the South Fork Jocko River. The terrain is characterized by steep elevation changes, ranging from the high point at Jocko Lookout down to the water-rich valley floor. Notable aquatic features include the high-altitude White Horse Lake and Meadow Lake, while the namesake Belmore Sloughs occupy the central basin near the Lake Co Missoula Co boundary.

Logistics across this mountainous environment were primarily limited to a network of established Pack Trails, which provided the only access between the river forks and remote water bodies like Lower Jocko Lake. This survey illustrates the area just as aerial photogrammetry became the standard for mapping such difficult terrain, recording the watershed of Falls Creek and Deep Creek before major modern development.
