Lake Superior is home to hundreds of shipwrecks, resting beneath the waters of the largest freshwater lake in the world by surface area. These wrecks range from massive steel freighters and early steamships to vessels that disappeared during violent storms and were not discovered for decades. Together, they preserve a remarkable record of the Great Lakes’ long and sometimes dangerous shipping history.
Lake Superior’s vast size, powerful storms, high waves, dense fog, rocky coastline, and extremely cold water created serious challenges for ships throughout the history of commercial navigation. Before modern weather forecasting, navigation technology, and communication systems, changing conditions could leave crews with little time to respond. Some vessels were damaged by storms or collisions, while others vanished suddenly with little or no trace.
Today, many Lake Superior shipwrecks remain underwater, while others have been located and explored by divers, sonar surveys, and underwater technology. Some are remarkably well preserved because of the lake’s cold, fresh water, offering a rare glimpse into the vessels and maritime history of the past.

How Many Shipwrecks Are in Lake Superior?
Lake Superior is believed to contain hundreds of shipwrecks, although there is no single confirmed total for every vessel that has been lost beneath the lake. Estimates commonly place the number at more than 500 shipwrecks, while historical records continue to be updated as researchers identify previously unknown wrecks. Some vessels were lost without leaving enough evidence to determine their exact location, and others may still remain undiscovered on the lakebed.
The difficulty in establishing an exact number comes partly from the lake’s enormous size. Lake Superior covers about 31,700 square miles, with vast areas of deep water that are difficult to survey. Older shipwrecks can also be difficult to locate because historical records may be incomplete, vessels sometimes disappeared without survivors, and wreck sites can be scattered far from modern shipping routes.
The known wrecks represent more than a century of commercial and industrial activity on Lake Superior. Steamships, bulk freighters, schooners, passenger vessels, and other working craft carried iron ore, grain, lumber, and other cargo across the lake. Some sank close to shore, while others went down in deep offshore waters during storms, collisions, fires, or other accidents.
Not all of Lake Superior’s shipwrecks have been discovered or explored. Modern sonar surveys, remotely operated vehicles, and other underwater technologies continue to reveal wreck sites that were previously unknown. As exploration expands, the recorded number of known wrecks can change, making “more than 500” a useful broad estimate rather than a definitive final count.
Why Does Lake Superior Have So Many Shipwrecks?
Lake Superior has so many shipwrecks because heavy ship traffic historically combined with some of the most challenging conditions found on the Great Lakes. For more than a century, commercial vessels crossed the lake carrying iron ore, grain, lumber, and other cargo. As the number of ships increased, so did the opportunities for accidents, particularly before modern weather forecasting, navigation systems, and communication equipment became widely available.
Severe storms are one of the most important reasons ships were lost on Lake Superior. The lake is large enough for winds to travel long distances and generate powerful waves. During major storms, waves can become high enough to pound vessels, damage their structures, shift cargo, or make steering difficult. Sudden changes in wind direction and wave conditions could be especially dangerous for ships already far from a safe harbor.
Cold water also made accidents more serious. A vessel that was damaged or sank could leave its crew in extremely cold water, particularly during the late fall and winter shipping seasons. Even when people survived the initial sinking, prolonged exposure to cold water could quickly become life-threatening. The cold freshwater also helped preserve some wrecks for remarkably long periods, allowing researchers to study vessels that sank many decades ago.
Fog and poor visibility created another major navigation hazard. Dense fog could obscure coastlines, islands, other vessels, and navigational landmarks, increasing the risk of collisions or grounding. This was particularly challenging for earlier ships that relied heavily on visual navigation and less sophisticated equipment.
Lake Superior’s rocky coastline, reefs, shoals, and narrow approaches to ports also contributed to ship losses. A vessel damaged by heavy weather could be driven toward dangerous shoreline features, while mechanical problems or navigation errors could result in grounding. Once a ship began taking on water or suffered serious structural damage, reaching a safe harbor could be difficult.
The lake’s enormous size further increased the consequences of an accident. Ships could be many miles from shore when trouble developed, leaving crews with limited options for immediate assistance. Together, heavy historical shipping, severe storms, powerful waves, poor visibility, cold water, and difficult navigation created the conditions that left hundreds of vessels on the bottom of Lake Superior.

SS Edmund Fitzgerald
The SS Edmund Fitzgerald is the most famous shipwreck in Lake Superior and one of the best-known maritime disasters in the Great Lakes. The 729-foot American steel bulk carrier was built by Great Lakes Engineering Works at River Rouge, Michigan, and launched on June 8, 1958. At the time, she was the largest ship on the Great Lakes and later became known as the “Queen of the Lakes.” During her 17-year career, the Fitzgerald primarily carried iron ore and taconite pellets between Lake Superior and industrial ports on the lower Great Lakes.
On November 9, 1975, the Fitzgerald departed Superior, Wisconsin, carrying 26,116 long tons of taconite pellets bound for Detroit. The following day, the vessel encountered a powerful November storm while crossing eastern Lake Superior. Weather conditions deteriorated rapidly, with strong winds and heavy seas creating extremely difficult conditions for the freighter and the vessels traveling nearby. By the evening of November 10, the Fitzgerald disappeared without sending a distress call, taking all 29 crew members with her.
The wreck was located in May 1976 using side-scan sonar and subsequently examined with an underwater remotely operated vehicle. The Fitzgerald was found in about 530 feet of water, roughly 17 miles northwest of Whitefish Point, with the ship resting in two major sections on the lakebed. The discovery confirmed the identity of the wreck and provided researchers with the first detailed opportunity to examine the remains of the lost freighter.
The precise sequence of events remains debated, but official investigations identified massive flooding of the cargo hold as the probable cause of the sinking. The U.S. Coast Guard concluded that the flooding most likely occurred through ineffective hatch closures as heavy seas washed over the vessel. The investigation also led to recommendations concerning Great Lakes load-line requirements, hatch and vent closures, and the maintenance and inspection of watertight openings.
The disaster became one of the defining tragedies in Great Lakes maritime history and was immortalized by Canadian singer-songwriter Gordon Lightfoot in his 1976 song “The Wreck of the Edmund Fitzgerald.” The ship’s 200-pound bronze bell was recovered from the wreck in 1995 and is now displayed at the Great Lakes Shipwreck Museum at Whitefish Point as a memorial to the 29 crew members who were lost.
SS Kamloops
The SS Kamloops was a 250-foot Canadian package freighter built in 1924 for Canada Steamship Lines. The vessel carried packaged freight between Montreal and ports around Lake Superior, transporting a mixed cargo that included food, clothing, machinery, wire, shoes, and other supplies. She was relatively new when she disappeared during the final weeks of the 1927 navigation season.
On December 7, 1927, the Kamloops was crossing Lake Superior as a major winter storm brought high winds, heavy seas, freezing temperatures, and poor visibility. The vessel was last seen in the vicinity of Isle Royale and was never heard from again. All 22 people aboard were lost. In the months that followed, the bodies of several crew members were found along the shores of Isle Royale, providing evidence that at least some of those aboard had reached the island before dying from exposure. One of the most haunting pieces of evidence was a message in a bottle written by assistant stewardess Alice Bettridge, apparently after she had reached Isle Royale. The note revealed that she was freezing and starving and believed she was the last person alive.
For decades, the location of the wreck remained unknown. On August 21, 1977, Minneapolis sport divers Ken Engelbrecht and Randy Saulter located the Kamloops near Twelve O’Clock Point on Isle Royale after conducting a systematic search guided partly by an earlier fathometer reading. Subsequent dives confirmed the ship’s identity, and the wreck was found lying on its starboard side in roughly 270 feet of water.
The Kamloops remains remarkably intact and undisturbed in the cold waters of Lake Superior, with portions of its cargo still visible inside the wreck. The combination of cold freshwater and great depth has helped preserve the vessel and its contents for nearly a century, making the site an important underwater record of Great Lakes shipping. Today, the wreck is protected within Isle Royale National Park and is recognized as one of the park’s most significant historic shipwrecks.
SS Bannockburn
The SS Bannockburn was a 244-foot Canadian steel-hulled freighter built in England in 1893. She spent much of her career carrying grain on the Great Lakes and was operated by the Montreal Transportation Company. On her final voyage, the vessel left Fort William, now part of Thunder Bay, Ontario, on November 20, 1902, carrying about 85,000 bushels of wheat bound for Georgian Bay. After a minor grounding delayed her departure, the Bannockburn resumed her voyage across Lake Superior the following day.
On November 21, the Bannockburn was sighted by Captain James McMaugh of the upbound SS Algonquin during difficult weather. McMaugh watched the vessel through binoculars for several minutes and saw her proceeding on what appeared to be a normal course. When he looked again, however, the Bannockburn had suddenly disappeared from view. Later that night, another vessel, the Huronic, reportedly saw lights resembling those of the missing freighter during the storm, but no distress signal was received. The Bannockburn never reached Georgian Bay, and all 22 people aboard were presumed lost.
The disappearance left almost no physical evidence. The wreck has never been located, and no bodies were recovered. A life preserver was among the few confirmed objects associated with the missing vessel, leaving researchers with no wreck site from which to determine exactly how she was lost. The combination of her sudden disappearance, severe November weather, and absence of a known wreck eventually turned the Bannockburn into one of Lake Superior’s enduring maritime mysteries.
Because the vessel vanished so completely, the Bannockburn soon became known as the “Flying Dutchman of the Great Lakes.” Stories of ghostly sightings of a steamer resembling the missing vessel became part of Great Lakes folklore, although these accounts cannot establish what actually happened to the ship. More than a century later, the Bannockburn remains one of Lake Superior’s best-known undiscovered shipwrecks, with its final location and exact cause of sinking still unknown.
SS Western Reserve
The SS Western Reserve was a 300-foot American steel bulk freighter launched in Cleveland in 1890. Built by the Cleveland Shipbuilding Company for shipping magnate Captain Peter G. Minch, she was among the first Great Lakes freighters constructed with steel plate and was the largest bulk carrier on the lakes when launched. Her speed earned her the nickname “Inland Greyhound,” and her steel construction represented an important step in the transition from wooden to steel Great Lakes freighters.
On August 30, 1892, the Western Reserve was traveling upbound toward Two Harbors, Minnesota, where she was scheduled to load iron ore. The vessel was sailing in ballast rather than carrying a cargo when a powerful gale struck about 60 miles northwest of Whitefish Point. At around 9 p.m., the ship suddenly broke in two and sank within minutes. Captain Minch, his wife, children, and members of the crew were aboard, and all 28 people escaped into two lifeboats. One lifeboat capsized shortly after being launched, while the second remained afloat through the night before eventually overturning near shore. Only wheelsman Harry W. Stewart survived.
The wreck remained undiscovered for more than 130 years. In late summer 2024, the Great Lakes Shipwreck Historical Society located the Western Reserve about 60 miles northwest of Whitefish Point using side-scan sonar. A remotely operated vehicle later confirmed the identity of the wreck in approximately 600 feet of water. The ship was found in two major sections, with the bow resting on top of the stern, providing striking physical evidence that the vessel had indeed broken apart as described by the sole survivor.
The discovery also renewed interest in why such a highly regarded steel vessel broke apart so suddenly. Historical accounts indicate that the ship was considered one of the safest and most advanced freighters of its time, while later research has examined the role that early steel construction and the stresses of heavy seas may have played in the disaster. Today, the Western Reserve remains an important Lake Superior shipwreck because it represents both the rapid development of steel Great Lakes shipping and one of the lake’s most tragic early maritime disasters.
SS Cyprus
The SS Cyprus was a 420-foot American steel bulk freighter built by the American Ship Building Company in Lorain, Ohio. She was launched on August 17, 1907, and entered service only weeks before her loss. After completing her first voyage carrying iron ore, the newly built vessel returned to Superior, Wisconsin, to load another cargo for the East. On October 9, she departed with iron ore bound for Lackawanna, New York, making the voyage that would become her last.
On October 11, 1907, the Cyprus encountered a severe storm off Deer Park, Michigan, about 35 miles west of Whitefish Point. As the weather worsened, the vessel began taking on water and developed a dangerous list before capsizing and sinking. Of the 23 people aboard, only second mate Charles G. Pitz survived. He managed to remain with a life raft for hours before reaching shore near the Deer Park Life-Saving Station. The other 22 crew members were lost, although most of their bodies were later recovered along the shoreline.
The exact sequence that caused the Cyprus to founder was never conclusively established. However, another freighter had reportedly observed a red wake behind the vessel before the sinking, suggesting that water was mixing with iron-ore dust in the cargo hold. Investigators and later researchers focused attention on the ship’s relatively new sliding steel hatch covers, which could allow water to enter if they were not adequately secured and protected. The loss of the Cyprus also contributed to a change in Great Lakes safety practice requiring tarpaulins over cargo hatches after September 1 for vessels sailing on the open lakes.
The wreck remained undiscovered for nearly a century. In August 2007, the Great Lakes Shipwreck Historical Society located a large wreck while searching with side-scan sonar north of Deer Park. Researchers initially suspected that they had found the SS D.M. Clemson, which had disappeared in the same general area in 1908, but an ROV examination of the stern revealed the name Cyprus and confirmed the identity. The ship lies on her port side in about 460 feet of water and remains remarkably intact, with sections of her hull, interior fittings, machinery, and scattered iron ore still visible around the wreck.
SS Emperor
The SS Emperor was a 525-foot Canadian steel bulk freighter built by the Collingwood Shipbuilding Company in Collingwood, Ontario. Launched in 1910 and placed into service in 1911, she was the largest ship ever built in Canada at the time and spent much of her career carrying bulk cargo, particularly iron ore, on the Great Lakes. By 1947, the vessel had been in service for more than three decades and was operated by Canada Steamship Lines.
On June 3, 1947, the Emperor unloaded coal at Fort William, Ontario, before moving to Port Arthur to load iron ore. She departed later that night carrying 10,429 tons of ore in five cargo holds and was bound for Ashtabula, Ohio. Shortly before 4:15 a.m. on June 4, the freighter struck Canoe Rocks at the northeastern end of Isle Royale. She developed a severe list and sank within about 20 to 35 minutes. Of the 33 people aboard, 12 were lost and 21 survived. The survivors were rescued by the U.S. Coast Guard Cutter Kimball, which was nearby working on navigation lights.
The official investigation focused heavily on the condition of the first mate, James Morrey, who had taken the watch shortly after midnight. Morrey had supervised the loading of the Emperor before departure, leaving him with little opportunity to rest during the hours when he would normally have been off duty. Investigators concluded that he was probably overtired and may have fallen asleep during his watch, allowing the ship to stray from its intended course and strike Canoe Rocks. Captain Eldon Walkinshaw was among those who died and was last seen on the bridge as the ship went down.
Today, the SS Emperor remains one of the best-preserved large shipwrecks at Isle Royale. The wreck is basically intact, with the bow showing the most damage, while the stern retains its mast, rudder and propeller, engine room, and numerous cabins. The site ranges from roughly 25 feet of water at the shallowest point to about 170 feet at the deepest portions, creating a dramatic underwater profile. The Emperor was added to the National Register of Historic Places in 1984 and is now protected within Isle Royale National Park as an important part of the area’s maritime heritage.
SS Henry Steinbrenner
The SS Henry Steinbrenner was a steel Great Lakes bulk freighter built by the Jenks Shipbuilding Company in Port Huron, Michigan, and launched in 1901. Originally operated by the Kinsman Transit Company of Cleveland, the vessel spent more than five decades carrying bulk cargo on the Great Lakes. Her long career was marked by several serious accidents, including a collision that sank the vessel in the St. Marys River in 1909 before she was raised, repaired, and returned to service. By the time of her final voyage in 1953, she had become one of the lake’s veteran freighters.
On May 10, 1953, the Steinbrenner departed Superior, Wisconsin, carrying a full load of iron ore bound for Cleveland, Ohio. The following day, the freighter encountered severe weather on Lake Superior. Heavy seas battered the vessel, and some of her telescoping hatch covers apparently loosened, allowing water to enter the cargo holds. The flooding became uncontrollable, and the Steinbrenner eventually foundered about 15 miles south of the Isle Royale Light Station. Of the 31 people aboard, 17 lost their lives while 14 were rescued by nearby vessels.
For decades, the location of the wreck remained unknown. In September 2023, shipwreck hunters Jerry Eliason and Ken Merryman located the Steinbrenner after a lengthy search in the waters south of Isle Royale. The wreck was found upright in approximately 750 feet of water, far deeper than many of the better-known recreational shipwrecks around Isle Royale. Its discovery finally provided a physical location for one of Lake Superior’s major 20th-century shipwreck mysteries.
The deep-water environment has also helped preserve the vessel remarkably well. The wreck and the surrounding field of spilled iron ore provide researchers with an opportunity to study both the ship and the circumstances of its loss. Today, the Steinbrenner stands as a reminder of the hazards faced by Great Lakes freighters even after navigation and communication technology had advanced considerably, and of the continuing ability of modern sonar and underwater exploration to locate long-lost wrecks.
SS Samuel Mather
The SS Samuel Mather was a 246-foot wooden bulk freighter built in Cleveland, Ohio, in 1887 by Thomas Quayle’s Sons. During her short four-year career, she carried bulk cargo on the Great Lakes, including coal and grain. On her final voyage, however, she was carrying about 58,000 bushels of wheat from Duluth, Minnesota, toward Buffalo, New York. Her loss would become an important example of the dangers faced by the wooden freighters that once dominated Great Lakes shipping.
On November 21, 1891, the Samuel Mather was traveling through Whitefish Bay in heavy fog when she was struck on her starboard side near the aft hatch by the steel freighter Brazil. The collision opened a large hole in the Mather’s hull, and the damaged vessel sank in about 25 minutes. The accident occurred roughly 8 miles from Point Iroquois. All 20 members of the Mather’s crew escaped in lifeboats and were picked up by the Brazil, so there was no loss of life in the sinking.
The wreck was discovered in May 1978 and now rests upright in the Whitefish Point Underwater Preserve. Much of the vessel remains remarkably well preserved, including its deck and stern structure, making the Mather a rare surviving example of a late-19th-century wooden Great Lakes freighter. The wreck extends from about 155 feet at the deck to roughly 180 feet at the lakebed, and its condition has made it a well-known site for experienced divers.
Artifacts recovered from the wreck are now held by the State of Michigan and displayed on loan at the Great Lakes Shipwreck Museum at Whitefish Point. The wreck itself is protected as part of the Whitefish Point Underwater Preserve, allowing researchers and divers to study one of the best-preserved wooden freighters remaining in Lake Superior.
SS Chester A. Congdon
The SS Chester A. Congdon was a 532-foot American steel bulk freighter built in 1907 as the Salt Lake City by the Chicago Shipbuilding Company. The vessel was sold to the Continental Steamship Company in 1912 and renamed after Chester Adgate Congdon, a prominent Duluth lawyer and financier. With a capacity of more than 10,000 tons, the freighter was among the largest bulk carriers operating on the Great Lakes during its era.
On November 6, 1918, the Chester A. Congdon left Fort William, Ontario, carrying about 380,000 bushels of wheat bound for Port McNicoll, Ontario. After encountering heavy seas near Thunder Cape, Captain Charles J. Autterson temporarily turned back for calmer water. When the vessel resumed its voyage, thick fog developed, and the ship eventually ran aground on the southern reef of Canoe Rocks near Isle Royale at about 1:08 p.m. The grounding seriously damaged the vessel, but all 36 crew members survived.
Salvage crews began removing wheat from the damaged freighter, but worsening weather soon made the operation impossible. On November 8, a strong gale with winds reaching about 55 mph battered the stranded vessel, and the Chester A. Congdon broke in two aft of its No. 6 hatch. The stern sank into deeper water while the forward section remained on the reef. The ship was declared a total loss, and contemporary officials valued the vessel and associated losses at more than $1.5 million, making it one of the largest financial losses ever sustained on the Great Lakes at the time.
Today, the wreck lies across Congdon Shoal at Canoe Rocks within Isle Royale National Park. The site includes an intact pilot house and bow section on the south side of the reef and an intact stern on the north side, with additional wreckage scattered between them. The Chester A. Congdon was listed on the National Register of Historic Places in 1984 and remains one of the major historic shipwrecks protected within Isle Royale National Park.
SS Gunilda
The SS Gunilda was a 195-foot luxury steel steam yacht built in Scotland in 1897. After being acquired by wealthy Standard Oil investor William L. Harkness, she became one of the most luxurious private vessels operating on the Great Lakes. In August 1911, Harkness, his family, friends, and crew were cruising along the northern shore of Lake Superior when the yacht headed toward Rossport, Ontario, before a planned trip into Lake Nipigon.
As the yacht approached Rossport, the Gunilda ran hard aground on McGarvey Shoal, on the northwestern side of Copper Island. Harkness had declined the services of a local pilot, and after the grounding he remained behind to supervise the salvage operation while the passengers were taken safely to Rossport. The tug James Whalen was brought in to free the yacht, but the salvage operation went badly. After the Gunilda was pulled from the shoal, she suddenly heeled to starboard, took on water through open openings, and sank into deep water. No one aboard was killed in the sinking.
The wreck was rediscovered in 1967 and rests upright on an even keel in about 270 feet of water. Its cold, clear freshwater environment has preserved the yacht exceptionally well. Much of the superstructure remains intact, along with both masts, the compass binnacle, furniture, and other interior fittings. A grand piano also remains inside the wreck, giving divers an unusual glimpse of the luxury of an early-20th-century Great Lakes yacht.
The Gunilda has attracted repeated salvage and exploration attempts since its discovery. In 1980, Jacques Cousteau and the Cousteau Society visited the wreck aboard Calypso and used the diving saucer SP-350 Denise to examine and film it. The wreck’s extraordinary preservation has since made it one of the most celebrated shipwrecks in Lake Superior, although its depth places it beyond the reach of ordinary recreational diving and makes it primarily a site for experienced technical divers.
SS George M. Cox
The SS George M. Cox was a steel passenger steamship built in Toledo, Ohio, in 1901 by the Craig Shipbuilding Company. Originally named Puritan, the 233-foot vessel was designed for overnight passenger service and could accommodate hundreds of passengers. She was lengthened to 259 feet in 1908 and continued operating in the Great Lakes passenger trade. During World War I, the U.S. Navy purchased the vessel and commissioned her as the USS Puritan, using her as a troop transport before returning her to civilian service in 1920.
After being laid up during the Great Depression, the Puritan was purchased by the Isle Royale Transportation Company in 1933 and given a major luxury refit. The vessel was repainted white, refurbished for passenger service, and renamed George M. Cox after millionaire businessman George M. Cox. Her first voyage under the new name began in May 1933, generating considerable excitement after the ship had spent several years out of service.
On May 27, 1933, the newly renamed George M. Cox was traveling through dense fog near the western end of Isle Royale when she struck Rock of Ages Reef near the Rock of Ages Lighthouse. The impact drove the ship hard onto the reef, but all 127 people aboard survived. Lifeboats were brought to the rocky outcropping near the lighthouse, where the survivors found refuge while efforts were considered to salvage the stranded vessel. Days later, worsening weather caused the ship to break apart, slide from the reef, and sink into Lake Superior.
Today, the wreck lies scattered across the reef, with twisted steel plating, exposed machinery, and the propeller remaining visible on the lakebed. The wreckage extends through relatively shallow water, with the site reaching roughly 10 to 100 feet in depth, while a National Park Service mooring buoy is attached to the ship’s boiler at about 45 feet. The George M. Cox is one of the major historic shipwrecks protected within Isle Royale National Park and is a popular site for divers exploring the park’s underwater maritime history.
SS Arlington
The SS Arlington was a 244-foot Canadian steel bulk carrier built in 1913 by the Detroit Shipbuilding Company in Wyandotte, Michigan. During her career, the vessel operated under several names, including F.P. Jones and Glencadam, before being renamed Arlington in 1936. By the time of her final voyage, she was an aging Great Lakes freighter carrying bulk cargo between Canadian and American ports.
On April 30, 1940, the Arlington left Port Arthur, Ontario, fully loaded with wheat bound for Owen Sound, Ontario. She was traveling across Lake Superior alongside the larger freighter Collingwood when dense fog developed and later turned into a severe storm. As the weather deteriorated, First Mate Junis Macksey ordered the Arlington toward the Canadian North Shore, where the shoreline would have offered some protection from the wind and waves. Captain Frederick “Tatey Bug” Burke, however, countermanded the order and directed the vessel back across the open lake. Around 4:30 a.m. on May 1, the Arlington began taking on water, and the crew abandoned ship without waiting for orders from the captain. All 16 crew members reached the Collingwood safely, but Burke remained aboard. He was reportedly last seen near the pilothouse, waving toward the Collingwood shortly before the Arlington disappeared beneath the lake.
Burke’s decision to remain aboard became one of the enduring mysteries surrounding the sinking. There was no clear reason why he did not join the rest of the crew, and later accounts could not establish whether he intended to remain with the vessel or simply waited too long to escape. The wreck was eventually found about 35 miles north of Michigan’s Keweenaw Peninsula in roughly 650 feet of water, providing the first physical evidence of the ship’s final resting place more than eight decades after the disaster.
The discovery was made in 2023 after shipwreck researcher Dan Fountain identified a promising anomaly while studying remote-sensing data from Lake Superior. Working with the Great Lakes Shipwreck Historical Society, Fountain and a research team aboard the R/V David Boyd surveyed the site with side-scan sonar and then used a remotely operated vehicle to confirm that the submerged wreck was the Arlington. The discovery finally solved the location of one of Lake Superior’s long-standing shipwreck mysteries, although the exact reason Captain Burke stayed aboard remains unknown.
SS D.M. Clemson
The SS D.M. Clemson was an American steel bulk freighter built in 1903 by the Superior Shipbuilding Company in West Superior, Wisconsin. Operated by the Provident Steamship Company of Duluth, Minnesota, the vessel carried bulk cargo such as coal, iron ore, and grain on the Great Lakes. During her relatively short career, the Clemson experienced several serious mishaps, including a near-sinking in 1905 and a collision with the piers at Ashtabula, Ohio, in 1908, before disappearing on Lake Superior later that same year.
On November 30, 1908, the Clemson passed through the Soo Locks after leaving Lorain, Ohio, carrying a cargo of coal bound for Duluth, Minnesota. Under Captain S. R. Chamberlain, the freighter entered Lake Superior just as a powerful winter gale was developing. She was last seen near Whitefish Point as the storm intensified, and the vessel failed to reach Duluth. All 24 people aboard were lost, making the disappearance one of the major maritime disasters on Lake Superior at the time.
Wreckage from the missing freighter began appearing along Michigan’s Upper Peninsula shoreline in the days following the storm. Debris, including life preservers and parts of the vessel, washed ashore near Crisp Point and Whitefish Point, while the remains of at least one crew member were recovered. The scattered evidence indicated that the Clemson had been lost somewhere in the eastern part of Lake Superior, but no survivor remained to describe what happened during the storm. Despite numerous searches over the years, the main wreck has never been located.
The disappearance of the D.M. Clemson remains one of Lake Superior’s enduring shipwreck mysteries. In 2007, researchers searching for the Clemson discovered a large unidentified wreck north of Deer Park, Michigan, but the vessel was later identified as the SS Cyprus, which had sunk in 1907. The Clemson itself remains undiscovered beneath Lake Superior, leaving its exact location and the precise circumstances of its final sinking unknown.
SS Vienna
The SS Vienna was a 191-foot wooden Great Lakes steamer built in Cleveland, Ohio, in 1873. She was constructed during an era when many Great Lakes steamers still carried sail rigging and spent much of her career hauling bulk cargo. The vessel had already experienced serious trouble before her final loss, including a sinking in Lake Superior in 1876 when she was only three years old. After being salvaged and rebuilt, the Vienna returned to service and continued operating on the Great Lakes for another 16 years.
On September 17, 1892, the Vienna was traveling downbound through Whitefish Bay while carrying a cargo of iron ore and towing the schooner barge Mattie C. Bell. At about 12:25 a.m., she encountered the upbound steamer Nipigon, which was towing two schooners. The two steamers exchanged signals for a normal port-to-port passing maneuver, but the Nipigon suddenly veered and struck the Vienna on her port side. The collision severely damaged the Vienna, and both vessels released their tows as the Nipigon attempted to save the stricken steamer.
The Nipigon towed the damaged Vienna toward shallow water for about an hour, but the effort was unsuccessful. The vessels were still roughly a mile from shore when the heavily damaged, ore-laden Vienna sank into deep water. All of the Vienna’s crew were safely transferred to the Nipigon, and no lives were lost. The reason the Nipigon suddenly veered from the expected course was never clearly established, adding an unusual element to the circumstances surrounding the collision.
The wreck was discovered in 1975 and now rests within the Whitefish Point Underwater Preserve in about 120 to 148 feet of water. Much of the vessel has deteriorated, but the stern remains prominently upright while the bow has collapsed, and divers can still see portions of the ship and scattered artifacts on the lakebed. The cold, clear waters of Lake Superior have helped preserve the wreck, making the Vienna an important example of a 19th-century wooden Great Lakes vessel and a popular historic dive site.
SS Leafield
The SS Leafield was a 249-foot steel-hulled bulk freighter built in Sunderland, England, in 1892 by the Strand Slipway Company. Originally registered in England, the vessel was purchased by the Algoma Central Steamship Company in 1900 and brought into Great Lakes service. She primarily carried bulk cargo between Canadian ports, including coal, grain, iron ore, and steel products. By 1913, the Leafield was being used in the steel-rail trade between Sault Ste. Marie, Ontario, and Fort William, Ontario.
On November 9, 1913, the Leafield was making her way across Lake Superior during the catastrophic Great Storm of 1913, one of the most destructive storms in Great Lakes maritime history. She was carrying a cargo of steel rails from Sault Ste. Marie toward Fort William when the storm brought powerful winds, heavy seas, snow, and extremely poor visibility. The vessel was reported lost near the Angus Islands, off Thunder Bay, although the precise circumstances of her final moments remain uncertain. Some historical accounts indicate that she struck or grounded on the rocky islands before disappearing into deeper water.
All 18 people aboard the Leafield were lost. In the aftermath of the storm, searches and shoreline investigations provided evidence of the vessel’s disappearance, but no survivors remained to explain exactly how the ship was overwhelmed. The loss became one of numerous maritime tragedies associated with the November 1913 storm, which claimed several Great Lakes vessels within a matter of days.
More than a century later, the Leafield remains one of Lake Superior’s undiscovered shipwrecks. Historical records from the University of Detroit Mercy Marine Historical Collection noted that the hull had still not been located as of 2002, while later vessel-history records continue to list the wreck as undiscovered. Its disappearance illustrates how difficult it can be to locate vessels lost in Lake Superior, particularly when a ship goes down during extreme weather in deep and remote water.
How Lake Superior Became a Shipwreck Graveyard
Lake Superior’s reputation as a shipwreck graveyard developed alongside the rapid expansion of Great Lakes shipping during the 19th and early 20th centuries. The growth of iron-ore mining in Minnesota and Michigan created a steady demand for vessels carrying ore, coal, grain, and other cargo between inland ports and the industrial centers of the Great Lakes.
The opening and expansion of the Soo Locks greatly increased the movement of commercial vessels between Lake Superior and the lower Great Lakes. As shipping traffic grew, vessels increasingly traveled through exposed parts of the lake, including the approaches to Whitefish Bay, the Keweenaw Peninsula, and the waters around Isle Royale. These routes connected major commercial ports but also placed ships in some of the lake’s most difficult navigational environments.
Isle Royale became particularly notorious because vessels had to navigate around reefs, rocky points, islands, and narrow passages. The strait between Passage Island and Blake Point, for example, was recognized as a dangerous route as early as the 19th century. As commercial traffic continued to increase, accidents accumulated over generations, leaving behind the large concentration of shipwrecks that makes Lake Superior one of the world’s most important freshwater maritime archaeological regions.
Where Are the Shipwrecks in Lake Superior?
Lake Superior’s shipwrecks are scattered across a vast area, with many lying near major historical shipping routes, rocky shorelines, islands, and harbor approaches. Some wrecks are close enough to shore to be explored by divers, while others rest hundreds of feet below the surface in remote parts of the lake. Their locations reflect the routes ships followed and the hazards they encountered.
One of the most important concentrations of wrecks is around Isle Royale, a large island in the northwestern part of Lake Superior. The island is surrounded by reefs, shoals, rocky points, and narrow passages that could be difficult for ships to navigate, particularly in fog or heavy weather. Numerous vessels were lost in the waters around the island, and many of their wrecks are now protected within Isle Royale National Park.
Another well-known area is the eastern end of Lake Superior near Whitefish Point, Michigan. Whitefish Point extends into the lake along an important historical shipping route and has long been associated with shipwrecks. The waters offshore include the wreck of the SS Edmund Fitzgerald as well as numerous other vessels lost during storms, groundings, and other accidents.
Shipwrecks can also be found around the Keweenaw Peninsula and along other rocky sections of Michigan’s Upper Peninsula. The peninsula projects into Lake Superior and creates a large area of exposed shoreline that historically required careful navigation. Storms, fog, reefs, and changing water conditions made these waters particularly challenging for vessels traveling along the lake’s commercial routes.
Other wrecks are scattered across the open lake, sometimes far from modern ports or easily accessible shorelines. These offshore sites can be particularly difficult to locate because of Lake Superior’s enormous size and depth. Some wrecks have been found only after extensive searches using sonar and other underwater surveying technology.
The distribution of shipwrecks therefore follows no single pattern. Some are concentrated around navigational hazards and busy shipping corridors, while others lie in deep offshore water where vessels were overwhelmed by storms or suffered unexpected failures. Together, these scattered wreck sites form an extensive underwater record of Lake Superior’s maritime history.
How Are Lake Superior Shipwrecks Discovered and Preserved?
Many Lake Superior shipwrecks remained hidden for decades because the lake is enormous, deep, and often difficult to survey. Researchers now use modern sonar, underwater cameras, remotely operated vehicles, and other technologies to locate wrecks and document their condition. Historical shipping records, newspaper reports, weather accounts, and information from surviving crew members can also help researchers narrow down where a missing vessel may have sunk.
Side-scan sonar is one of the most useful tools for searching the lakebed. It can produce detailed images of objects resting on or projecting above the bottom, allowing researchers to identify shapes that may correspond to a shipwreck. Once a possible wreck site is located, divers or remotely operated vehicles can investigate the remains and compare them with historical records to determine the vessel’s identity.
Lake Superior’s cold, fresh water can preserve underwater wrecks remarkably well. The low temperatures slow biological processes that would normally cause wooden structures and other materials to deteriorate more quickly. As a result, some shipwrecks retain recognizable hulls, cargo, equipment, and other features even after many decades underwater.
Preservation does not mean that wrecks remain unchanged. Metal eventually corrodes, wooden components can weaken, and storms or underwater currents can damage exposed structures. Human activity can also pose a threat when artifacts are removed or wreck sites are disturbed. For this reason, many significant wrecks are treated as protected archaeological and historical resources.
One of the most important areas for shipwreck research is Isle Royale National Park, where numerous historic wrecks are protected as part of the park’s maritime heritage. Researchers and divers can study these sites while following regulations designed to protect the wrecks and their artifacts.
Modern exploration continues to reveal new information about Lake Superior’s maritime past. Newly located wrecks can help researchers understand how ships were built, what cargo they carried, where they traveled, and how they were lost. In this way, the lake’s shipwrecks serve not only as reminders of maritime disasters but also as underwater historical records of Great Lakes shipping.
Conclusion
The shipwrecks in Lake Superior tell the story of more than a century of Great Lakes shipping and the challenges faced by the vessels that crossed its waters. From the legendary SS Edmund Fitzgerald to wrecks that remained hidden for generations, each vessel reflects a different combination of weather, navigation, mechanical problems, accidents, and the demanding conditions of commercial transportation.
Lake Superior’s enormous size, powerful storms, high waves, fog, rocky waters, and extremely cold water made some voyages particularly hazardous, especially before modern navigation and weather forecasting. At the same time, the lake’s cold freshwater environment has preserved many wrecks remarkably well, allowing researchers and divers to study these underwater remnants of maritime history.
Many wrecks have now been located, but others remain undiscovered somewhere beneath the lake. As sonar technology and underwater exploration continue to improve, new discoveries can add to our understanding of the ships, crews, cargoes, and events that shaped Lake Superior’s maritime past.
