Symbols of safety, reassurance, and guidance, lighthouses hold a special fascination for many people. On the Great Lakes, lighthouses--"northern lights"--helped to open the region to settlement and support the growth of commercial trade. Charles K. Hyde describes the histories of more than 160 individual lighthouses that still exist on Lakes Erie, Huron, Michigan, and Superior and the straits of Mackinac. As the shipping industry flourished, so too did the necessity for lighthouses. With their proliferation came a demand for more sophisticated structures. Hyde describes the changing design of lighthouses and the equipment that produces their beacons. Featuring over two hundred color photographs, The Northern Lights captures the beauty, history, and significance of lighthouses on the Great Lakes and illuminates the rich maritime history of the region.
