Geography

Split Rock Lighthouse State Park encompasses about of rocky shoreline on Lake Superior with several prominent headlands. Named features of the shore, from southwest to northeast, are the mouth of the Split Rock River, Split Rock Point, Crazy Bay, Corundum Point, the mouth of Split Rock Creek, Day Hill, Little Two Harbors, Stony Point (site of the lighthouse), and Gold Rock Point.State of Minnesota, Department of Natural Resources.

Cultural history


Early history

Several vestiges of early 20th-century industry are visible in the park. The first white settlement in the Split Rock area was Little Two Harbors, a commercial fishing village populated largely by Norwegian immigrants. The men of the village fished for trout, whitefish, and
herring Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, i ...
from 16–18 foot skiffs in the fall and winter. Little Two Harbors was inhabited until 1925, although in later years only 4 or 5 residents lived there year-round. Cement foundations of houses and fish processing buildings remain. A logging camp known as Splitrock existed at the mouth of the Split Rock River from 1899 to 1906. Pilings from their dam and wharf are still visible jutting from the water. The Merrill Logging Trail follows the route of their rail line. In 1901 a prospector from Duluth misidentified the outcrops of anorthosite as

. Three years later the North Shore Abrasives Company set up mining operations on Corundum Point, but abandoned the site in 1908 when their product was found to be inadequate. Their crushing house burned down in a forest fire in 1910 but its concrete footings remain. Another remnant from this period is a finely crafted, freestanding stone fireplace atop Day Hill. According to local legend it was the start of a house built around 1900 by Frank Day, a businessman from Duluth, for himself and his sweetheart, but abandoned when she did not reciprocate his love.Minnesota Department of Natural Resources.

''. The ''Edenborn'' was beached far ashore at the mouth of the Split Rock River and later salvaged, but one of the 25 crewmembers was killed. The ''Madeira'' with 10 men aboard drifted northeast until violent waves began smashing her against the cliffs of Gold Rock Point. Crewman Fred Benson managed to leap onto the rocks and scale the cliff in the midst of the snowstorm. The first mate was swept overboard and drowned, but Benson was able to lower a rope and pull the other eight crew to safety. The ''Madeira'' sank in pieces at the foot of Gold Rock while the crewmen, suffering from exposure and frostbite, found shelter with local fishermen and loggers. Both crews were picked up two days later by the tugboat '' Edna G''. The shipping companies that had sustained losses in the storms lobbied the federal government for an expanded system of navigational aids on the Great Lakes. Besides the ''Edenborn'' and the ''Madeira'', five other ships had been damaged within a dozen miles of the Split Rock River. A signal in that area was at the top of the industry's list of demands. The site ultimately selected for the lighthouse and fog signal was northeast of the Split Rock River, on Stony Point. There were no roads yet up the North Shore, so all construction materials were brought in by barge and hoisted up the cliff with a

built a new access road and lighthouse tenders were provided with a truck to bring in supplies by land, so the tramway was dismantled. The picturesque lighthouse, perched on a 130-foot cliff overlooking the world's largest lake, began attracting small numbers of visitors within weeks of its opening. However the completion of Highway 61 opened the floodgates to tourism. In 1938 it was estimated that 100,000 visitors stopped by, five times more than any other federally operated lighthouse. Some of the lighthouse keepers' children opened a souvenir stand just outside the station entrance in 1941. Both the U.S. Lighthouse Service and the

and other technology had rendered it obsolete. However, by 1967 the Coast Guard was considering decommissioning the station. The state legislature acted to expand the wayside into a full-fledged state park including the lighthouse itself. The station was officially closed in 1969 after 59 years of service. Under the Surplus Property Act the grounds and buildings were transferred to the state of Minnesota for free to be operated as a historic site. The state parks division developed an entrance station, picnic grounds, roads, and trails. The Minnesota Historical Society took over management of the lighthouse station in 1976. Over the next decade they restored several buildings to their 1920 appearance and constructed a $1.2 million history center. Meanwhile, from 1984 to 1990 the state park spent $555,000 to improve the recreational facilities, including a new access road, picnic area, and all-season trail shelter, and an expanded trail system. They also developed the park's first campground, an unconventional design in which campers wheel their equipment to their sites in carts provided by the park. The Split Rock Trading Post, just outside and unaffiliated with the state park, operated from 1960 up to 1999, when it burned down in a fire. In addition to a kitschy gift shop, this

Gold Rock Point, the headland just north of the lighthouse, was not originally part of the state park. In 1997 it was purchased from its private owners by the Parks & Trails Council of Minnesota, an organization founded by Clarence Magney, among others, to buy and hold worthy properties until state legislation can authorize their public acquisition. The next year Nadine Blacklock, a nature photographer and president of the Parks and Trails Council, was killed in a car accident just outside the north end of the park. The Council and the Blacklock Nature Sanctuary, an art and conservation non-profit organization she and her family had founded, jointly purchased of land around the accident site. were transferred to the state park while the remainder, with an existing one-bedroom cabin, is managed by the Blacklock Nature Sanctuary as an artists' retreat. The additions were developed with access features for ''Madeira'' wreck divers and the Gitchi-Gami State Trail, a paved bicycling route in development along the North Shore.


Recreation

Split Rock Lighthouse State Park has a unique cart-in campground with 20 secluded campsites and a modern restroom. Campers leave their vehicles in a parking lot and use two-wheeled carts provided by the park to carry their equipment a short distance to their site. There are four backpack campsites along the shore, two accessible to sea kayakers. Conventional drive-in campgrounds managed by the state park are available in two state forests in the area. An expansion of the state park campground, to include 60 drive-in sites, has been approved and construction may begin in summer 2010. The park contains of trails for hiking, bicycling, and cross-country skiing. There are several overlooks providing views of the lighthouse and Lake Superior. A paved section of the
