Can you buy a map of the bottom of the Great Lakes, how they are shaped and what they look like. | ||

Yes, go to a good boating store. They have depth charts for all the waterways in the US. | ||

There's some maps online that show this. Looks like you can order posters from them as well. http://www.ngdc.noaa.gov/mgg/g reatlakes/greatlakes.html http://www.ngdc.noaa.gov/mgg/g reatlakes/michigan.html | ||

IIRC, Lake Superior is by far the deepest (over 1,300 ft.), followed by Lake Michigan (over 900 ft. deep)... followed by Lake Ontario (over 700 ft. deep)... then Lake Huron at about 583 ft. deep, with Lake Erie by far the shallowest at only 208 ft. deep. | ||

"IIRC, Lake Superior is by far the deepest (over 1,300 ft.), followed by Lake Michigan (over 900 ft. deep)... " Which, of course, means that the deepest depths of those lakes are well below sea level. That fact always fascinated me for some reason. | ||

Spiritofdetroit... I have this quirky (but useless) ability to remember statistics! Hell if I can remember that 3 of the most massive mountains in the continental US, about 800 miles from each other, only have about a 85 ft. difference in elevation! Mt. Whitney in CA - 14,495 ft. tall (highest in the Sierra Nevada) Mt. Elbert in CO - 14,431 ft. tall (highest in the Rockies) Mt. Rainier in WA - 14,411 ft. tall (highest in the Cascades) ... then it tells ya that I'm nuts!  (Message edited by Gistok on January 30, 2008) | ||

If they only did NOT have categories on rock music, hollywood personalities, English Lit, or poetry (which they always have at least one of) I'd be an undefeated Jeopardy! champ. | ||

Little_buddy, if I understand your question, you’re thinking of a relief type of map similar to the Michigan map in the link below, correct? http://www.worldmapsonline.com /hs960michiganstatemaprr.htm If that’s the case, I don’t know of any companies commercially selling such a map for the underwater topography of the Great Lakes. There is the fabulous giant map in the Dossin Museum showing the underwater topography of the Great Lakes. There’s also a giant version of the Niagara Escarpment in the museum at the Visitors Centre at Lock 3 in St. Catharines in Ontario (it’s on the Welland Canal). | ||

"Which, of course, means that the deepest depths of those lakes are well below sea level." Just out of curiosity...why is that surprising? After all, the shallowest part of every ocean is also below sea level, i.e., below the surface of the sea. The fact that Lakes Superior, Michigan etc. are below sea level at their deepest points doesn't mean that they are anywhere near as deep as the deepest parts of the ocean. Even the bottom of the Mississippi River at New Orleans is nearly 200 feet below sea level. | ||

I've also found that interesting mainly because we're 570-600 feet above sea level on the upper lakes. But what I find more interesting is that the bottoms of Superior and Ontario are below the average depth of the Continental Shelf. Rampart... Do you mean 20 feet? I'm pretty sure the Mississippi isn't 200 feet deep. And again it makes sense to be below sea level at sea level but as high as we are is where the interest factor comes in. | ||

The Mississip has to be more than 20 ft. deep at Nawlin's...but 200 sounds awfully high. I always thought Jimmy went into an Eastern Market area rendering plant and became dog food. Does anyone know the depth of Lake St. Clair? | ||
Elsuperbob Member Username: Elsuperbob Post Number: 111 Registered: 03-2007 |
Lake St. Clair is 21 feet deep at its deepest, naturally, but because that's too shallow for shipping it has a 27 feet deep shipping channel. | ||
Elsuperbob Member Username: Elsuperbob Post Number: 112 Registered: 03-2007 |
Apparently 200 is correct which is much deeper than I would have thought. And to me that is just as amazing as the lake facts. I know the Amazon is deeper than that at the mouth but didn't think the Mississippi had near enough flow to get close. But then it isn't nearly as wide so that's where the difference comes in. | ||

I was looking at a map of the Mackinaw Straits and you can clearly see the remains of the river that once flowed through there. It was really cool to see. | ||

The Mississippi at New Orleans bends into a tight "U" shape--the flow of the river is from left to right in this pic. The deepest part of the River (approx 200 feet deep) occurs at the outside of the sharp bend shown in this photo where the river's current has carved an underwater canyon into the wall of the river bank. If you ever ride one of the tour boats there you will see whirlpools on the surface as a result of the turbulence beneath.  | ||

My sources say Lake Huron's maximum depth is 750 ft. For instance see: http://www.michigan.gov/deq/0, 1607,7-135-3313_3677-15926--,0 0.html |
