Both a community and a water fall. The waterfall is a cascade with a 19-foot descent; at its foot is Dudenay Trail, one of the most often used of the fur-traders’ trails. David Thompson, who twice made the trip to the falls, recorded the name of the Indians of the region, the Kalispelus.
Metaline Falls occupies a rocky, sloping bench on the east bank of the Clark Fork River. The town was founded in 1910, and the promotion of the Mammoth and Morning mines brought the first settlers to the site. Silver, lead, cement materials, fire clay, and lime were found in this region.
Mining activities, as elsewhere in the state, have known periods of boom and decline.
The Grange and the Nonpartisan League have considerable strength in the Metaline Falls vicinity. It was said that, in its time, the I.W.W. had great influence in this region, even among the farmers.Important plants were those of the Lehigh Cement Company, the Pend Oreille Mines and Metal Company, American Lead and Zinc Company, and the Metaline Mining and Smelting Company. Two hydroelectric plants supplied power for municipal and industrial use. Today Metaline Falls is no longer an industrial center, but has maintained an impressive collection of early twentieth century structures. Part of the Lehigh Cement Company Plant still looms prominently.
