Congress is a census-designated place (CDP) in Yavapai County, Arizona, United States. The population was 1,717 at the 2000 census. Congress, a gold-mining ghost town, now serves as a retirement and bedroom community for nearby Wickenburg.
Gold was discovered at Congress in 1884. By 1893, the Santa Fe Railroad passed within three miles of the mine, at Congress Junction. Congress boomed, and remained prosperous until the mid-1930s, when the mines closed. Total gold production at the Congress Mine exceeded $8 million, at the then-current price of $20.67 per ounce—or about $400 million, at the 2007 price.
The post office moved to Congress Junction in 1938, where it remains. The community now known as Congress is the old Congress Junction. Little remains at the original townsite. Source:
