Thank you Ruby for this and one of many lighthouse cards that you have sent me. This card shows the Split Rock lighthouse on the coast of Lake Superior..
THE SPLIT ROCK LIGHTHOUSE STATE PARK:is a State Park of Minnesota on the shores of Lake Superior.and is best known for its "Split Rock Lighthouse " which is one of the most photographed lighthouses in the United States.
This light house was first lit in 1910 The beacon of The Split Rock lighthouse guided the mariners across the dark and treacherous waters of western Lake Superior for over 50 years. The 3rd order Fresnel lens is seven foot across and weighs seven and a half tons and was made in Paris France of many cut glass prisms. Originally used with a kerosene lamp., when the light station was electrified in 1939 the light was furnished with a 1000 watt bulb. The official range of the light is 22 miles but has been seen from as far away as 60 miles. The light station is now administered by the Minnesota Historical Societ and visitors may climb the 33 steps to the top of the tower.
