Idaho towns list more on the Register than most of the country (a typical Idaho town has 8.4 per 10,000 residents, the U.S. 2.4), so St. Maries’ 13.7 sits near the middle of its state (60% of Idaho towns have fewer) while its 4 listings outnumber those of 68% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±7.2 points). The founding year is the first post office, not a stated founding date.

The story

How St. Maries came to be

From Wikipedia’s history of St. Maries.

Read it all →

The townsite was selected by Joseph Fisher, just southwest of the confluence of St. Maries River and St. Joe River, to provide a location for a sawmill, first built in 1889. The rivers and lake systems provided rapid transportation systems for floating logs to the mills and utilizing steamboats to transport finished products to market. From the city, the St. Joe River flows west, through several lakes and into the south end of Lake Coeur d'Alene.

The Pacific Extension of the Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road) arrived in 1908. The city was established in 1913 when Benewah County was formed from southern Kootenai County. In 1915 St. Maries was named its county seat.
