Why isn't there an English name for this region? Because it's arbitrary & unimportant to the people who live there. This is an important lesson in toponymy. Indigenous place names cover the land in detail, but colonizers are often confounded why so few Indigenous regional names.

Jacques Cartier - "What's this land called?"⠀
Natives - "IDK man, but this is our kaná:ta' (village)."⠀
Cartier - "Got it. The land of Canada."⠀
⠀
Or more recently, we hear a lot of "What do natives call Australia/Florida/The Philippines/British Columbia?"⠀

The question is really what do colonizers call the place where the river begins to quicken? Or where the migratory birds land in Spring? Or where that rock is shaped like an ancestor? The answer is nothing. They have no name because they don't have a relationship with the land.

The names that appear on maps represent the big places, not the small ones. The big places are defined by and thus named by colonizers, but they are no less Indigenous land.
