You'll see Ghost Towns on your drive through the Heart of the Country. The miners were the first of the pioneers to come to this region. The prospectors came before there were roads and railroad tracks. Because of the wealth that these spectacular mountains yielded, others followed, towns were established, and roads and railroads came to the mountains. Had it not been for the rich ore and the prospectors, this beautiful region would probably have remained uninhabited.
