Kerr, MT

Kerr is a Lake County census-designated place on the southwest side of Polson, where the Flathead River leaves Flathead Lake. That river exit is the key to the local map: the community sits beside the lake-to-river transition, while Polson supplies the county-seat frame just to the north. The surrounding story is tied to the older landing at Polson, where a ferry crossed the Flathead River in 1864 and later trading posts grew around the crossing. Kerr itself is best read as the lake-and-river edge of the Polson area, with Lake County geography shaping the larger map. The local shorthand is lake outlet, river, Polson, and county-seat country.
