I read this on a FB post….lots of interesting facts about our great fresh-water lake system…

Things You Probably Never Knew About The Great Lakes.....
1. Lake Superior is actually not a lake at all, but an inland sea .
2. All of the four other Great Lakes, plus three more the size of Lake Erie, would fit inside of Lake Superior.
3. Isle Royale is a massive island surrounded by Lake Superior. Within this island are several smaller lakes. Yes, that’s a lake on a lake.
4. Despite its massive size, Lake Superior is an extremely young formation by Earth’s standards (only 10,000 years old).
5. There is enough water in Lake Superior to submerge all of North and South America in 1 foot of water.
6. Lake Superior contains 3 quadrillion gallons of water (3,000,000,000,000,000). All five of the Great Lakes combined contain 6 quadrillion gallons.
7. Contained within Lake Superior is a whopping 10% of the world’s fresh surface water.
8. It’s estimated there are about 100 million lake trout in Lake Superior. That’s nearly one-fifth of the human population of North America!
9. There are small outlets through which water leaves Lake Superior. It takes two centuries for all the water in the lake to replace itself.
10. Lake Erie is the fourth-largest Great Lake in surface area, and the smallest in depth. It’s the 11th largest lake on the planet.
11. There is alleged to be a 30- to 40-foot-long “monster” in Lake Erie named Bessie. The earliest recorded sighting goes back as early as 1793.
12. Water in Lake Erie replaces itself in only 2.6 years, which is notable considering the water in Lake Superior takes two centuries.
13. The original publication of Dr. Seuss’s The Lorax contained the line, “I hear things are just as bad up in Lake Erie.”
Fourteen years later, the Ohio Sea Grant Program wrote to Seuss to make the case that conditions had improved. He removed the line.
14. Not only is lake Erie the smallest Great Lake when it comes to volume, but it’s surrounded by the most industry.
Seventeen metropolitan areas, each with populations of more than 50,000, border the Lake Erie basin.
15. During the War of 1812, the U.S. beat the British in a naval battle called
the Battle of Lake Erie, forcing them to abandon Detroit.
16. The shoreline of all the Great Lakes combined equals nearly 44% of the circumference of the planet.
17. If not for the the Straits of Mackinac, Lake Michigan and Lake Huron might be considered one lake.
Hydrologically speaking, they have the same mean water level and are considered one lake.
18. The Keystone State was one of the largest and most luxurious wooden steamships running during the Civil War.
In 1861, it disappeared. In 2013, it was found 30 miles northeast of Harrisville under 175 feet of water.
19. Goderich Mine is the largest salt mine in the world. Part of it runs underneath Lake Huron, more than 500 meters underground.
20. Below Lake Huron, there are 9,000-year-old animal-herding structures used by prehistoric people from when the water levels were significantly lower.
21. There are massive sinkholes in Lake Huron that have high amounts of sulfur and low amounts of oxygen, almost replicating the conditions of Earth’s ancient oceans 3 million years ago. Unique ecosystems are contained within them.
22. Lake Huron is the second largest among the Great Lakes, and the fifth largest in the world.
23. In size, Lake Michigan ranks third among the Great Lakes, and sixth among all freshwater lakes in the world.
24. Lake Michigan is the only Great Lake that is entirely within the borders of the United States.
25. The largest fresh water sand dunes in the world line the shores of Lake Michigan.
26. Because water enters and exits Lake Michigan through the same path, it takes 77 years longer for the water to replace itself than in Huron, despite their similarity in size and depth. (Lake Michigan: 99 years, Lake Huron: 22 years)
27. When the temperature of Lake Michigan is below freezing, this happens.
28. Within Lake Michigan there is a “triangle” with a similar reputation to the Bermuda Triangle, where a large amount of “strange disappearances” have occurred. There have also been alleged UFO sightings.
29. Singapore, Mich., is a ghost town on the shores of Lake Michigan that was buried under sand in 1871. Because of severe weather conditions and a lack of resources due to the need to rebuild after the great Chicago fire, the town was lost completely.
30. In the mid-19th century, Lake Michigan had a pirate problem. Their booty: timber. In fact, the demise of Singapore is due in large part to the rapidly deforested area surrounding the town.
31. Jim Dreyer swam across Lake Michigan in 1998 (65 miles), and then in 2003, he swam the length of Lake Michigan (422 miles).
32. Lake Michigan was the location of the first recorded “Big Great Lakes disaster,” in which a steamer carrying 600 people collided with a schooner delivering timber to Chicago. Four hundred and fifty people died.
33. Lake Ontario is the smallest of the Great Lakes in surface area, and second smallest in depth. It’s the 14th largest lake on the planet.
34. The province Ontario was named after the lake, and not vice versa.
35. In 1804, a Canadian warship, His Majesty’s Ship Speedy, sank in Lake Ontario. In 1990, wreck hunter Ed Burtt managed to find it.
Only, he isn’t allowed to recover any artifacts until a government-approved site to exhibit them is found. He’s still waiting.
36. Babe Ruth hit his first major league home run at Hanlan’s Point Stadium in Toronto. It landed in Lake Ontario and is believed to still be there.
37. A lake on Saturn’s moon Titan is named after Lake Ontario.

The deepest parts of Lakes Superior, Michigan and Ontario are hundreds of feet below sea level.

Due to the counterclockwise current and prevailing westerlies throughout the summer, the Michigan shoreline gets all that warm water and beautiful fine sand beaches and sand dunes (Indiana, too, to some extent) on Lake Michigan. Wisconsin and Illinois suffer with frigid water and gravelly shorelines. For sure, some of the beaches are sandy on the western side, but only where the artificial groins capture the sand!

I asked the admiral if she wanted to hear some facts about the great lakes. I received a very disinterested look. Two minutes later she was glued to the screen. These are really fascinating! Great post!

As both a sailor and a diver , that list left off some very interesting facts about the shipping history of the Great Lakes .
There are more than 5000 shipwrecks in the Great Lakes . There are even trains on the bottom !

I found a book called “Wood on the bottom” at an AirBnB I was staying at in Grand Haven, Michigan. It documented many of the shipwrecks on the Great Lakes, and the heroic work of the Coast Guard when they were primarily shore based stations with row boats.

A very interesting collection of short stories.

IN 1822, John Jacob Astor took advantage of a protectionist law that banned foreign fur trading in U.S. territories and established the Robert Stuart House on Mackinac Island as the headquarters for American Fur Company. Intertwining his fur companies with inter-continental trading created profits that propelled him to become the wealthiest American of his time. The American Fur Company dominated fur trading in the US from the Great Lakes to the Pacific NW for the short period of time in the early 1800's.

Great info!! I saw 800’ on the the depth finder on Lake Ontario, leaving Sodus Bay NY, heading for Wapoos Ont. I usually see 400’ from Niagara to Toronto.
Wonder what’s down there?

Dark, very dark water. :yikes:

And in some places logs. Maybe 20 years ago I visited with some Oregon loggers. Discussing how logging got started in the Pacific NW. Folks who had lived in the Great Lakes were identified. When they had logged the great white pine forests of Wisconsin they moved west till they ran out of land, the theory goes. The Great Lakes provided a highway to transport logs East. Along the way logs were lost. Some of the logs are still persevered deep in lakes.

This is true. Of course it's a windward / leeward thing. I grew up the Lake Huron side of the mitten. Rock, Rocks, Rocks and more rocks. In the days before aqua socks you just tenderly walked out until you could float on your belly.

I honestly didn't know there were beaches that were not like that until I was an adult.
