Shipwrecks of the Great Lakes
2
Great Lakes Shipwreck Facts
  • More than 6,000 shipwrecks have occurred on the
    Great Lakes.
  • Approximately 25,000 people have lost their lives
    due to Great Lakes shipping related accidents.
  • 70 percent of the ships that sailed the Great
    Lakes in the 1800s wrecked.
  • The Great Lakes claim the highest concentration
    of shipwrecks on the planet.
  • Lake Erie claims the most wrecks, followed by
    Huron, Michigan, Ontario, and Superior.

Shipwrecks by Lake

Where Ships Wreck
  • Shipwrecks are primarily located in common
    shipping lanes where traffic is high.
  • Many shipping lanes are narrow making collisions
    more likely.
  • Shoals and sand bars often tightly border
    shipping lanes making navigation treacherous.

Reasons Ships Wreck
  • Storm
  • Fire or Explosion
  • Collision
  • Ice
  • Other

7
Percent of Shipwrecks Attributed to Each Cause
8
The Witch of November
  • Unpredictable and often violent late fall weather
    creates dangerous sailing conditions for Great
    Lakes ships.
  • October and November weather is responsible for
    most of the Great Lakes shipwrecks that have
    occurred due to storms.
  • Weather in November has been known to produce
    wave heights up to 30 feet.
  • These storms are also commonly referred to as the
    Gales of November.

9
Number of Ships that have Wrecked each Month due
to Storm
10
The Griffin
  • 70 foot sailing brig.
  • Built by LaSalle for exploration and fur trading.
  • Regarded as the first decked ship to sail the
    Great Lakes.
  • Sank in August of 1679 probably near the Straits
    of Mackinaw.
  • Entire crew of 6 lost.

11
Probable Location of the Griffin Wreck
12
The Regina
  • 296 foot steel package freighter.
  • Sank on November 10, 1913 in Lake Huron near Port
    Sanilac.
  • Entire crew of 20 lost.
  • Overwhelmed by the famous Big Storm of 1913
    which sank 71 vessels and killed 248 people.

13

14
The Carl D. Bradley
  • 623 foot, steel, self unloading limestone
    freighter.
  • Lost on Lake Michigan, 12 miles southwest of Gull
    Island, November 18, 1958.

15
  • The Bradley broke in two after fighting 30 foot
    waves and 65 mph winds.

16
  • 33 of 35 crew members lost.
  • 27 of the 35 crew resided in Rogers City, MI.

17
The Wreck of the Bradley
18
The Edmund Fitzgerald
  • 729 foot, steel, self unloading, iron ore
    carrier.

19
  • The Edmund Fitzgerald was the Flag Ship of the
    Oglebay Norton shipping company.

20
  • On November 10, 1975, after fighting 80 mph
    winds, 30 foot waves, and sustaining significant
    damage, the Ed Fitz sank near Lake Superiors
    Whitefish Point.

21
  • All 29 crew members were lost.
  • The longest and most capacious ship ever to sink
    on the Great Lakes

22

23
Fires and Explosions
  • Fuel leaks are the greatest cause of boat and
    ship fires.
  • Faulty electrical systems can spark a fire.
  • Careless human activity and arson have also
    caused a number of nautical fires.
  • Explosions are often due to boiler failures or
    cargo related issues.

24
The G.P. Griffith
  • 193 foot wood sidewinder passenger ship.
  • Lost in Lake Erie near Cleveland, June 17, 1850.
  • 200 to 325 lives lost.
  • Fire may have ignited from an illegal load of
    matches and turpentine.

26
The Noronic
  • 362 foot steel passenger ship
  • Burned on Lake Ontario while tied up in Toronto
    Harbor.
  • 119 passengers died.
  • The cause of the fire is believed to be arson.
  • The ship burned to a shell and was later scuttled
    in deep water.

28
Collisions
  • Heavy traffic areas such as bays and narrow
    shipping lanes contain a disproportionately large
    number of wrecks due to collision.
  • Many collisions can be attributed to fog which
    reduces visibility.

29
The Pewabic
  • 200 foot wood passenger ship.
  • Sank in Lake Hurons Thunder Bay on August 9,
    1865.
  • 100 lives lost.
  • Collided almost bows-on with her sister ship the
    Meteor while trying to pass messages and mail
    from one ship to the other.

31
The Cedarville
  • 588 foot steel, self-unloading, iron ore
    freighter.
  • Sank on May 7, 1965 in Lake Huron. The wreck lies
    3 miles east of the Mackinaw Bridge.
  • Collided with a Norwegian freighter while
    underway in fog.
  • 10 of 31 crew lost.

33
Ice
  • Ships can become trapped in ice and have their
    hull crushed or run into drifting ice gouging
    their hull open.
  • Ice would also freeze parts of ships such as the
    rudder, or weigh down the deck of a ship, causing
    it to sink.
  • 75 of ice related shipwrecks have occurred in
    the spring.
  • Almost all of the ships that sank due to ice were
    made of wood.

34
The Aurania
  • 352 foot steel bulk freighter
  • Sank on April 29, 1909 in Lake Superior near
    Parisienne Island.
  • No loss of life. The crew walked to another
    ship.
  • Got trapped in pack ice and the hull was slowly
    crushed

36
Unusual and Freak Accidents
  • Many ships have been lost for reasons not known
    or due to freak and unusual occurrences.
  • Some rare occurrences that have been documented
    include hull failures, capsizing in calm seas or
    at dock, and strandings.

37
The Eastland
  • 296 foot steel passenger vessel.
  • Sank on July 24, 1915 in Chicago Harbor.

38
The Wreck of the Eastland
39
  • The Eastland capsized while tied up at dock as
    passengers were boarding.
  • The capsizing was attributed to the fact that the
    ship was top heavy and the ballast tanks that
    distribute the ships weight were mismanaged.

40
  • Eventually the Eastland rolled completely over
    trapping many below and within the ship.
  • In all, 844 people were lost due to the accident.
    Only 3 were crew.

41
The Onoko
  • 287 foot, four-masted, steel, steam powered,
    cargo vessel.
  • Lost on Lake Superior near Duluth Minnesota,
    September 15, 1915.

42
  • Was the largest ship on the Great Lakes when
    built in 1882.
  • Was the first metal bulk carrier on the Great
    Lakes.

43
  • While traveling on Lake Superior, she lost a hull
    plate under the engine room
  • The ship immediately began to sink
  • The rush of cold water caused the boiler to
    explode.

44
The Wreck of the Onoko
45
  • All 18 crew and the ship mascot, a bulldog,
    survived.
  • As the Onoko sank, she rolled and now lays upside
    down under 220 feet of water.

46
The Mesquite
  • 180 foot steel Coast Guard Cutter
  • Wrecked on December 9, 1989 near Lake Superiors
    Keweenaw Peninsula.

47
The Wreck of the Mesquite
48
  • With the end of the shipping season near, the
    Mesquite was retrieving the remaining
    navigational buoys from Lake Superior
  • A series of navigational errors caused the ship
    to drift off course and run aground becoming
    stranded.

49
  • Believing that the Mesquite would weather the
    winter, the Coast Guard waited until spring to
    salvage the cutter.
  • When spring came, significant ice and weather
    related damage was discovered.

50
  • She was later stripped of her superstructure,
    towed into deep water, and sunk to become part of
    a new underwater preserve
