1935 Map of Thompson Lakes

About this map

The Kootenai River snakes through the mountainous terrain of the Kootenai National Forest, serving as a vital corridor for the Great Northern Railway as it follows the river’s bend toward Jennings. This mid-1930s survey illustrates a landscape defined by timber and mineral extraction, most notably at the Vermiculite Mine near Vermiculite Mtn. Settlements like Warland and Fleetwood dot the northern reaches, while the southern valleys are characterized by isolated educational outposts and forestry management sites.
