Long a crossroads for Native Americans, in 1805, the Lewis and Clark Expedition portaged the great falls of the Missouri. Early development combined electrical power from dams with mineral resources from nearby mountains to power smelters and refineries. The railroad stimulated growth as Great Falls became a dynamic "Electric City" at the heart of the mountains and valleys of Cascade County. Today the river, ranching and farming, regional retail, and medical facilities combine with cultural and recreational tourism and Montana's largest military presence. Great Falls boasts Montana's greatest ethnic diversity, with the state's largest Native American and African American populations. A world-class symphony and the renowned Charles M. Russell Museum help round out Great Falls as Montana's "All-American City."
