Sanders County

Sanders County is an administrative county in western Montana that extends between the Bitterroot Mountains to the south and Cabinet Mountains to the north. The territory is traversed by the Clark Fork River and contains several small communities, with Thompson Falls serving as the county seat.

Montana established Sanders County in 1905 as a new administrative unit in the region. Thompson Falls was designated as the administrative center and has shaped county development since then.

The Sanders County Fair in Plains presents annual rodeo events that demonstrate the local agricultural traditions and community connections.

The administrative center in Thompson Falls provides public services for residents and visitors, including property records and document searches. Most visitors will find information about office hours and local services there.

The Clark Fork River divides the territory into zones with different rainfall patterns, creating varied landscape types across the county. This natural division creates contrasting environments within the same administrative area.
