Saw someone post an unsourced image with "the Great Lakes' real names", so just a reminder that there are lots of Indigenous languages and the many different nations have called them different things at different times.
Also, in general but especially, as I understand, regarding Indigenous knowledge, it is important to say *who* you learned something from.
Here's a map of the Great Lakes area with place names in Anishinaabemowin (Ojibwe), from the Decolonial Atlas, prepared by Charles Lippert and Jordan Engel: https://decolonialatlas.wordpress.com/2015/04/14/the-great-lakes-in-ojibwe-v2/ These lakes have additional names not given on the map itself but listed in the text; for example Lake Ontario is also called Gichi-zaaga’igan (Big Lake), and Lake Huron is also called Odaawaawi-gichigami (Odawa's Sea) and Gichi-aazhoogami-gichigami (Great Crosswaters Sea). Lippert also notes in comments, "The Anishinaabemowin on this map is shown written in 'Southern' Fiero-Nichols orthography, with more western 'Ojibwe' bias."
(Without getting specific enough to dox myself, I grew up near Anishinaabe communities and Anishinaabemowin is the language I don't know but can at least recognize, and which is often used here)
