Chewelah serves as the industrial and transport hub of the Colville River valley on this survey from the 1920s. The region's economy is clearly defined by its mineral wealth, anchored by the Northwestern Magnesite Plant and a concentrated cluster of workings such as the Amazon Mine, United Copper Mine, and Quartzite Mtn Magnesite Quarry. The Great Northern railroad tracks parallel the river, connecting the settlements of Addy, Valley, and Springdale to wider markets.
