Unlock the mystery of maritime navigation with Mary Habstritt of the Lilac Preservation Project. At night many of our waterways become constellations of flashing lights. These Aids to Navigation (or AtoNs) keep our marine traffic moving safely, but most of us have only the vaguest idea what they mean or what it takes to establish and maintain them. The Lilac, a steam-powered United States Lighthouse Service (later US Coast Guard) tender introduces the public to the world of AtoNs and helps us see our waterways with new insight.
