1966 Map of Thompson Lakes

About this map

The Thompson Lakes chain dominates this terrain within the Kootenai National Forest, where the waters of Upper Lake, Middle Lake, and Lower Lake create a distinct hydrological corridor. This 1966 survey, later revised to reflect the landscape of the early 1980s, highlights the recreational and natural resource character of the region. The map documents the presence of Logan Park Campground and several designated picnic areas along the lake margins, while the surrounding uplands like Meadow Ridge and Bowers Peak are accessible via routes such as the Barnum Trail. Localized industry is noted through scattered Gravel Pits near the shorelines. This sheet captures a critical intersection of three counties, marking the boundary where Lincoln, Flathead, and Sanders meet, and traces the flow of the Thompson River as it exits the lower lake.
