These photos were taken on one of the back roads in Minnesota that I explored in September. I believe that this is/was a root cellar.
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.
Construction began on in the Spring of 1891. The light was first lit on April 15, 1892...
The light tower and keeper's house are attached. This allowed the keeper to go directly from his house to the tower. The tower is built three bricks thick. The house is built two bricks thick. So where the walls meet is five bricks thick. The idea behind this thickness was, with the oil that was used in lighting the lamps in the tower, there was a level of protection provided the keeper and his family.
The tower is about 12 feet square and 49'6" tall.
