The Northern Pacific Railroad corridor was at the center of my exploration of Thompson Falls in 1984-1985 but I did not ignore either the man for whom the town was named nor the falls that has brought the town power for more than a century.
On the outskirts of town, the 1920s monument to David Thompson was the centerpiece of the town’s heritage tourism attractions in 1984-1985, now it is more of an afterthought. David Thompson was a Welsh-Canadian who established the first trading post in this river valley, called Saleesh House, for the tribe with whom this veteran of both the Hudson Bay Company and North West Company had targeted for the fur trade. His last visit to Saleesh House came in the winter of 1812. Thompson, I thought in 1984, was a very important figure in Montana history but increasingly a neglected trader–in fact most of the early traders, like those of the American Fur Company on the Missouri and Yellowstone Rivers, are neglected, even though significant places associated with them remain intact on the state’s landscape.
About one hundred years after David Thompson’s last winter at Saleesh House, an entirely different landscape emerged along the Clark’s Fork River, one that introduced the recent technology of electricity to the region. To support and encourage the development of hydroelectric facilities, the city of Thompson Falls combined with investors to build what became known as the “High Bridge,” a way for automobile traffic to cross this gorge in the Clark’s Fork and unite settlement on both sides of the river.
The High Bridge was an early 20th century Montana engineering marvel. It was 588 feet in length, designed for automobile traffic, with a 18-feet wide deck standing on a combination of Pratt and Parker trusses. It is the longest bridge of its kind in Montana.

The long bridge was closed c. 1980 to traffic, and it was just setting there, a huge structure neglected when I visited Thompson Falls in 1984. The adjacent Gallatin Street bridge, which provided access to the area, remained extant as well.
But within two years, residents and officials combined together to place the bridges and hydroelectric facilities in the National Register of Historic Places as a historic district. They were preserved, but still not used, for a generation.
In 2009-2010, residents worked with local, state, and federal government officials to restore the bridge, add a pedestrian deck, and to open the bridge and either side of the bridge as a public park. Funding in part came from the American Recovery and Reinvestment Act of 2009, one of the ways that short-lived federal building effort benefited historic preservation in Montana small towns.
The High Bridge experience not only reconnected Thompson Falls to its river roots, it also creates an unique experience for heritage travelers. The site is not that far different from 100 years ago, giving you the chance to cross a river and peer below but also to realize just how “wild” automobile traffic was in the 1910s and 1920s.
In my state historic preservation plan work of 1984-1985, Thompson Falls became one of my favorite stops. No one much in the professional field had been surveyed here yet, and then I was particularly interested in how the Northern Pacific Railroad transformed the late territorial landscape. As the image above shows, Thompson Falls was a classic symmetrical-plan railroad town, with a mix of one and two-story buildings from the turn of the 20th century. I focused on this commercial core.
The public meeting at the mid-20th century Sanders County Courthouse was well attended and most were engaged with the discussion: the pride, identity, and passion those in attendance had for their history and their interest in historic preservation was duly noted. The courthouse itself was not a concern–it dated to 1946 and wasn’t even 40 years old then. But now I appreciate it as a good example of Montana’s post-World War II modern movement, designed by Corwin & Company in association with Frederick A. Long
Little did I understand, however, that the sparks of a local community effort were already burning–and within two years, in 1986, Thompson Falls had placed many of its key historic properties in the National Register of Historic Places.

The old county jail (1907) has been transformed into a museum, both preserving one of the town’s oldest properties but also creating a valuable heritage tourism attraction. The contractors were Christian and Goblet, a local firm that had a part in the construction of the town’s building boom once it was designated as the county seat.

The mid-20th century Sanders County Courthouse is to the west of the commercial core and it marks how the town stretched to the west in the latter decades of the century.
Along with the conversion of businesses and the adaptive reuse of older buildings, Thompson Falls also has located key community institutions, such as the local library first established in 1921, along Main Street facing the railroad tracks.
But many community institutions–fraternal lodges such as the Masonic Lodge above, the public schools, and churches are on the opposite side of the tracks along the bluffs facing the commercial core. Thompson Falls is a very good example of how a symmetrical plan could divide a railroad town into distinctive zones.
Sanders County, like many of the places that are on the western side of the Rocky Mountains, has boomed in the last 25 years, from a population over 8,000 to the current estimated population of 11,300. It is close to Missoula, the eastern side is not far from Flathead Lake, Montana Highway 200 runs from Dixon to the end of the county at Heron. With wide valleys and narrow gorges created by both the Flathead and Clark’s Fork Rivers, which meet outside the town of Paradise, Sanders County is frankly a spectacular landscape, with dramatic mountain views framing open plains, such as the image above and the awesome gorge of Clark’s Fork River, below at Thompson Falls.
The eastern side of the county is just as dramatic just in a far different way. For centuries First Peoples hunted game and dug the camas root in the broad upland prairie that became known as Camas Prairie, crossed now by Montana Highway 28.
Then, leading from the county’s southeastern edge there is the beautiful Flathead River Valley, followed by Montana Highway 200, from Dixon to Paradise, and most importantly,
a transportation route initially carved as a trail by the First Peoples who became the nucleus of today’s Confederated Salish and Kootenai Tribe and much later engineered into a major corridor by the tracks of the Northern Pacific Railroad, as it stretched westward from Missoula to the west coast.
In its wake, the Northern Pacific created most of the county’s townsites by locating sidings along the track. Substantial settlement arrived once the federal government opened lands for the homesteading boom in the early 20th century.
Dixon, named for the former Montana governor Joseph Dixon, is one of the remaining railroad/homesteading towns along the Flathead River. The fate of the community bar, above, is symbolic of the recent history of the town, one of population decline.



Local residents are being excellent stewards of this captivating property–certainly one of my favorite spots in the state combining landscape with architecture with history. The architect was the Missoula designer H. E. Kirkemo, and the school was completed in 1940, near the end of the New Deal school building programs.



The school had just closed its doors for good when I lasted visited but the restoration planning has been underway ever since. I look forward to my next visit to Paradise to experience the final results. Near the school is another historic community property, the Paradise Cemetery, where tombstones mark the names of those who worked so long for the railroad and for the creation of this place within the Clark’s Fork River Valley.
