For anyone that didn’t know, Lake Superior is that deep because it is a failed mid-continental rift. That means that at some point, way in the past, North America almost split in two, and Lake Superior would have been another ocean between the two halves. This is what created the Keweenaw peninsula
The continent was actually Laurentia back then. Lake Ontario, the St Lawrence Valley and the Gulf of St Lawrence are all part of the same rift.
Lakes Michigan, Huron and Erie are all the shorelines of ancient seas that were ringed by coral. This left behind soft Calcite rock that the glaciers carved away.
this is the first time I have heard of this. Do you have a recommendation on this here to learn more about it?
@anachronist THANKS! Added it to my library book queue, only 321 books ahead of it bookwyrm.social/user/fu/books/…
I still think Michigan and Huron are one giant lake.
They’re all one lake if they’re touching. The river between them is just an extension of the lake.
Take this statement as seriously as you wish to.
Hydrologically Lake Michigan-Huron is one two-lobed lake. This is because the Straits of Mackinac is not a river.
Sorry, but could you post this with measurements that people can actually understand, like washing machines or carrots or something?
