1958 Map of Mount Bradley

About this map

The Middle Fork Flathead River serves as the dominant hydrological feature of this wilderness corridor, carving a deep path between the high peaks of the Flathead National Forest and Glacier National Park. This 1958 survey, updated with late-1970s Forest Service data, documents a landscape managed for conservation and remote backcountry access. Notable high-altitude crossings include Roosevelt Pass and Singleshot Pass in the north, while the southern reaches are marked by the Granite Forest Service Facility near the riverbank. The terrain is characterized by steep ridges like Patrol Ridge and glacial basins such as Tranquil Basin and Giefer Lake. The inclusion of the Great Bear Wilderness boundary reflects the evolving federal land management of the mid-20th century, capturing the area before modern recreational impacts altered these drainage networks.
