The safety of countless people has depended on lighthouses, beacons that cut through fog and darkness to alert seafaring souls of shores ahead. A former lighthouse keeper tells the dramatic stories of the sentinels that line the coast from California to British Columbia. Vintage and color photos of these lighthouses, coastal landscapes, and even tragic shipwrecks are presented as part of a narrative that focuses on human courage. As technology inexorably advances, the job of the lighthouse keeper is gradually being phased out. This is the twilight of the lighthouses' use for navigation, and this work is a tribute to a way of life that is an important part in the American maritime cultural fabric.
