late edit: DISCLAIMER: The pictured map is not actually a representation of the territories before colonisation. It's a hypothetical map of what countries there might have been had the continent not been colonised, thus all the names and borders are fictional and have never existed.
For good actual maps, check out native-land.ca.
I'm not sure about some of this, like Anasazi were not contemporaneous with the other tribes listed.
Looks like a fictional alternative timeline map.
If I'm not mistaken, the name too means "Ancient Enemies" in Navaho.
