The History of Flathead Lake
A Natural Wonder with a Rich Past
Flathead Lake, nestled in northwestern Montana, is the largest natural freshwater lake west of the Mississippi River. Spanning nearly 200 square miles, it was formed by ancient glaciers during the last Ice Age and has remained a breathtaking natural feature for thousands of years.
Native Lands and Cultural Roots
For generations, the lands around Flathead Lake have been home to the Salish, Kootenai, and Pend d’Oreille peoples. These tribes lived in harmony with the land, depending on the lake for food, water, and spiritual guidance. Today, the southern half of the lake remains within the Flathead Indian Reservation, honoring this deep-rooted connection.
Settlers, Railroads & Growth
In the 1800s, European-American settlers arrived, lured by fertile lands and the lake’s natural beauty. The arrival of the Great Northern Railway spurred growth, and towns like Polson, Bigfork, Somers, and Lakeside began to thrive. Agriculture, particularly cherry orchards, became a regional hallmark.
