Post Falls is located four miles east of the Washington-Idaho border along Interstate 90 and nearby Coeur d’Alene. It is in close proximity to numerous lakes, rivers and mountains, which makes it an inviting place to visit. Post Falls is located on the Spokane River and on the Coeur d’Alene branch of the Northern Pacific Railroad, eight miles south of Rathdrum and twenty-five miles east of Spokane.
It is in the center of quite an extensive agricultural, stock and fruit region, which every year becomes more productive. The falls in the river were formerly known as Little Falls, and Upper Falls; but the name was changed to Post Falls in honor of Frederick Post, the builder of the mill and founder of the town. It is said of Mr. Post: “Frederick Post does not need to be introduced to the people of northern Idaho by words. He has earned the encomium lavished by President Roosevelt on a leading citizen of the United States, ‘He is a man who has done things.’ Perhaps no man in this part of the inland empire has a better right to the leading place in the realm of real benefactor of the country than Frederick Post.”
