Marshall Point Lighthouse
Port Clyde, Maine (August 2009) The Marshall Point Lighthouse appears as the second lighthouse featured in this video I took while traveling around Port Clyde and Muscongus Bay in southeastern Maine (map). This lighthouse can be visited on an easily accessible stretch of the mainland. It also features a museum open to the public during…

Key West Lighthouse
Key West, Florida (April 2009) A light rose early in the history of Key West — 1826 — just seven years after the territory of Florida became part of the United States. The original brick structure of the lighthouse towered sixty-five feet above the southernmost point of the island, illuminating seaward through the power of…

Jones Point Light
City of Alexandria, Virginia, USA (2000) Only Jones Point light remains as a lighthouse on the Potomac River. It dates back to 1856. The land on which it rests returned to the Commonwealth of Virginia only ten years earlier. I mention this because I first stumbled across the Jones Point Light while conducting field research…

More South Florida Lighthouses
Broward and Monroe Counties, Florida (April 2009) The lighthouse at Hillsboro Inlet came to the coast rather recently, having been first lit in 1907 (map). This section of coastline sits at the northernmost reach of the Florida Reef and mariners needed sufficient warning when approaching the underwater coral to avoid damaging their vessels. This became…

Remote Lighthouses of the Dry Tortugas
Dry Tortugas National Park, Florida (April 2009) The end of the Florida Keys is not Key West. Not hardly. Islands of coral, sand and mangrove trail out further into the Gulf of Mexico. First come the Marquesas Keys. Further out still, some 70 miles from the civilized shores of Key West come the Dry Tortugas.…

Franklin Island Light
Muscongus Bay, Maine (August 2009) The Franklin Island light (map) is the first lighthouse featured in this video I took while traveling Muscongus Bay in southeastern Maine. There has been a lighthouse on this rock since 1807 — one of the earliest places along the Maine coastline to be lighted — although this current structure…

Fort Point Lighthouse
Stockton Springs, Maine (August 2009) Fort Point seems to be an odd name for a lighthouse but it makes perfect since once you understand the history of the area. There was once an older structure along this point on Cape Jellison at the mouth of the Penobscot River. Literally there was a fort here, Fort…

Fenwick Island Lighthouse & Transpeninsular Line
Fenwick Island, Delaware, USA (2008) A lighthouse rose above remote Fenwick Island in 1859. It filled a critical 60-mile gap between Cape Henlopen and Assateague Island (map). The structure housed a third order Fresnel lens with an 83 foot focal plane in its slender white tower. Amazingly the same Fresnel lens operates today. This stands…

Canal Park
Duluth, Minnesota (August 2007) Our journey through the upper Midwest brought us as far north as Duluth. Here a city rises along the westernmost deep-water port with access to the Atlantic Ocean. This is all the more surprising because it’s a good third of the way across the continent. Even so, ships — massively large…

Currituck Beach Lighthouse
Corolla, North Carolina (March 2012) Our trip to Currituck Beach Light provided a nice opportunity for a drive-by sighting. Unfortunately that’s the best we could do during the winter. It’s open and free to the public between Easter and Thanksgiving (with a small fee to climb the lighthouse tower). However it’s closed during the winter,…
