Au Sable Light is an activelighthouse in thePictured Rocks National Lakeshore west ofGrand Marais, Michigan offH-58. Until 1910, thisaid to navigation was called "Big Sable Light" (not to be confused withBig Sable Point Light[7] nearLudington, Michigan onLake Michigan orLittle Sable Point Light south ofPentwater, Michigan).
The Au Sable Light Station was built in 1874[8] on Au Sable Point, a well known hazard onLake Superior's "shipwreck coast". The Au Sable Pointreef is a shallow ridge of sandstone that in places is only 6 feet (1.8 m) below the surface and extends nearly 1 mile (1.6 km) into Lake Superior. The Au Sable Point reef was one of the greatest dangers facing ships coasting along the south shore of Lake Superior during the early shipping days when keeping land in sight was the main navigational method. The Au Sable Point reef was known as a "ship trap" that ensnared many ships, including the passenger shipLady Elgin which was stranded there in 1859.
The shoreline in this area is considered one of North America's most beautiful, "but in the 1800s it was considered one of the most deadly because of unpredictable features below the surface and violent storms and blinding fogs above."[9] The reef extends nearly a mile out as a ridge of sandstone a few feet below the surface. The shallow water caught many a vessel following the shore. Turbulence was common when the lake was "pushed in by violent storms out of the north and northwest." Thick fogs resulted form the mix of frigid lake air and warmth from the sand dunes. "As early as 1622, French explorers called the region 'most dangerous when there is any storms'."[10]
Additionally, the location was chosen to eliminate a "dark spot" in the 80 miles (130 km) stretch betweenGranite Island Light andWhitefish Point Light.[11]
The lighthouse tower and attached keepers' quarters were designed by ColonelOrlando Metcalfe Poe. In this capacity he designed eight "Poe style lighthouses" and oversaw construction of several. Poe was named District Engineer for the Eleventh Lighthouse District, Those lights areNew Presque Isle Light (1870) onLake Huron,Lake Michigan'sSouth Manitou Island Light (1872),Grosse Point Light (1873) inEvanston, Illinois,Lake Superior's Au Sable Light (1874),Racine, Wisconsin'sWind Point Light (1880);Outer Island Light (1874) in theApostle Islands,Little Sable Point Light (1874) on Lake Michigan,Manistique, Michigan'sSeul Choix Light (1895) andSpectacle Reef Light.[12]
The tower is a white brick conical tower with a black lantern. A red brick lightkeeper's house stands next to the lighthouse. It originally had a third-orderFresnel lens, which is now on display at the light station.[13] The lighthouse was automated in 1958 and is currently equipped with a 12-inch (300 mm)solar-powered light.
A wooden boathouse was added in 1875; thefog signal building was added in 1897; the keepers' quarters were converted to a duplex in 1909; and the steel oil house was raised in 1915. There is also a second brick Keepers house (1909), a kerosene storage shed (1895), two brickouthouses (1874/1909), a woodenwoodshed andboathouse (1875), a brick cistern, and a two vehicle wood frame garage (1954).[14] Most of these buildings are still extant; only one outhouse remains standing.[10][15]
Thekeeper's house was renovated. A visitor center is on the lower floor and an apartment for volunteer caretakers on the upper floor.[13]
In 1996, the original Third Order Fresnel lens was returned to the tower after 39 years on display at thePictured Rocks Nautical and Maritime Museum,[16] also known as theGrand Marais Maritime Museum[17] in Grand Marais. However, it is an external 300 mm lens that is operative.[13][18]
Thesteam whistle andairhorn have been removed. Nevertheless, the "boarded lantern area is an impressive sight."[18]
The lighthouse tower is open to the public in summer. The complex was maintained by theNational Park Service, and the automated light continues to be operated by theUnited States Coast Guard. The National Park Service's stated goal is to continue to maintain the lighthouse complex to its 1909–10 appearance, during its first year of operation as a two-personLighthouse keeper station.[7]
The Light Station is part of the National Park Service's Pictured Rocks National Lakeshore. The Au Sable Light Station is on theNational Register of Historic Places, #78000374.[4][7][18]
To visit this light, take
H-58 from the Hurricane River Campground, which is 12 miles (19 km) west ofGrand Marais, Michigan. From the Campground the lighthouse is a 1.5-mile (2.4 km) walk on a sand trail.[19][20]
