Sounds like a bad horror flick, but, in fact, over the last 100 years, many American lighthouses have been lost -- destroyed by the forces of nature and those of mankind. They are the victims of erosion, storms, earthquakes, war, and government demolition. With each light that burns out, we lose more of our country's treasured maritime history -- tales of shipwrecks, heroic captains, mutiny at sea, countless lives saved. A number of organizations throughout the United States are working to save other lighthouses from the same fate. Endangered Lighthouses tells the stories of fifty American lighthouses in peril, including their history, the dangers they face, and what efforts are being made to save them.
