History
Boundary County was formed on January 23, 1915, from
Bonner County. It was named Boundary County because it lies on the border of Canada, Washington and Montana.
Boundary County has seven election precincts: Bonners Ferry, Copeland, Kootenai, Moyie, Naples, North Bonners Ferry, and Valley View. All contain part of Bonners Ferry City except Copeland, Moyie, and Naples precincts. Moyie Springs was incorporated in 1947.
Settlement of the area started with the establishment of Bonners Ferry on the Kootenai River in 1864. Settlement was limited to the ferry operation until about 1890. The town of Bonners Ferry was established in 1893. At that point settlement was still sparse with small ranching and mining operations, but an expanding timber economy. By 1900, other areas started to develop with the Boulder (now Kootenai), Boundary (now Copeland), and Naples precincts first listed in the U.S. Census of that year. The Moyie precinct first appeared in the 1910 census.
In 1980, convicted
spy Christopher John Boyce found refuge in Boundary County, for a few months, after his escape from the
Lompoc Federal Correctional Complex. He stayed at the home of Gloria Ann White. Boyce sustained himself during his stay with a series of bank robberies in the surrounding area, allegedly with technical assistance from White.
In 1992, Boundary County was the scene of the
Ruby Ridge siege by 350–400 armed federal agents against
Randy Weaver and his family.
In April 2024, the city council of Bonners Ferry, the county seat of Boundary County, unanimously passed a resolution to continue flying the Canadian flag at its visitor center, despite state restrictions that threatened to remove all foreign flags from government properties. The resolution was seen as a symbolic gesture honoring the region’s historic and economic ties with neighboring British Columbia, especially amid growing tensions over state-level efforts to restrict certain displays of international symbols on public grounds.
