1Shipwrecks of the Great Lakes
2Great 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.
3Shipwrecks by Lake
4Where 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.

6Reasons Ships Wreck
- Storm
- Fire or Explosion
- Collision
- Ice

7Percent of Shipwrecks Attributed to Each Cause
8The 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.

on the Great Lakes
22The Wreck of the Edmund Fitzgerald
23Fires 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.
24The G.P. Griffith
- 193 foot wood sidewinder passenger ship.
- Lost in Lake Erie near Cleveland, June 17, 1850.
- 200 to 325 lives lost.

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.
27The Wreck of the Noronic
28Collisions
- 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.
29The 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

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.
32The Wreck of the Cedarville
33Ice
- 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.
34The 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
35The Wreck of the Aurania
36Unusual 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.
37The Eastland
- 296 foot steel passenger vessel.
- Sank on July 24, 1915 in Chicago Harbor.
38The 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.
41The 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.
44The 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.
46The Mesquite
- 180 foot steel Coast Guard Cutter
- Wrecked on December 9, 1989 near Lake Superiors
Keweenaw Peninsula.
47The 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
