In township of Split Rock, north shore of Lake Superior.

Picturesquely located at the top of an imposing rock jutting out into Lake Superior is Split Rock Lighthouse. The station derives its name from the appearance of the rock as it is approached from the open lake. The octagonal brick tower 54 feet in height was built in 1910. Because of the height of the rock, the light was 168 feet above the level of the lake and could be seen for 22 miles. An incandescent oil-vapor lamp was used inside the third-order lens, producing a light of 450,000 candlepower. The station was also equipped with a compressed air-operated diaphone fog signal, sounding a blast every 20 seconds in time of fog. Split Rock Lighthouse is one of the most frequently visited lighthouses in the United States. The light was discontinued in 1969. (1) (2)
