Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so St. Croix Falls’ 12.4 sits above most of its state (78% of Wisconsin towns have fewer) while its 3 listings outnumber those of 65% of U.S. towns.

What stands out about St. Croix Falls’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
In the 1840s, the land that would become St. Croix Falls was indirectly settled by Nordic and Scandinavian Americans and German Americans. After the increase of logging and the founding of the Cushing Land Company, St. Croix Falls became incorporated in 1887. The logging industry became important in St. Croix Falls, attracting New England immigrants which started a chain reaction of cutting down vast amounts of white pine. They were sent down the St. Croix River and the Mississippi River. From the late 1890s on, the logging industry died down; the last log cut at the Saint Croix log mill was in 1914. This made St. Croix Falls a more agricultural town.
Old hamlets and crossroads still carry their names on the map.
