About this map

The high mountain Divide between the Flathead National Forest and the Kootenai National Forest defines this landscape in Northwest Montana. This 1963 survey, which was updated with 1979 aerial photography, documents the remote drainage systems of Sylvia Lake and the various tributaries feeding into the Salish Mountains. The boundary between Lincoln Co and Flathead Co runs directly through the center of this terrain, crossing significant peaks such as Mount Conner and Sanders Mountain.

Navigation through these high-elevation forests relied heavily on an established Pack Trail network that connected isolated valleys. Named peaks like Ingalls Mountain and Grubb Mountain serve as primary landmarks for a region defined by its water sources, from the winding Wolf Creek to the smaller Squaw Meadows Creek. The map provides a detailed view of the natural topography before modern development, focusing on the watershed and the jurisdictional boundaries of the national forest system.
