Split Rock, The Superior Light relates the saga of the most visited and most photographed lighthouse on the Great Lakes. From the challenges of construction to the isolated life of the early keepers, Split Rock's story fascinates and delights. With the construction of Highway 61 along the Minnesota North Shore of Lake Superior, the keepers' duties expanded from tending the light station to becoming tour guides for thousands of eager tourists. Today, forty-plus years after decommissioning by the Coast Guard, Split Rock has become one of the most-visited historic sites in Minnesota. 2010 marks the centennial celebration of this landmark on Lake Superior.
