It was named for and is the site of the St. Ignatius Mission, established by Fr. Pierre-Jean De Smet, a Belgian Jesuit Catholic missionary who worked for his entire career in the American Midwest and West. The mission is listed on the National Register of Historic Places. In July 1919 the town was all but wiped out by raging forest fire. Only a bank, one store and a hotel, remained standing.
