As north as north and as south as south. The coastline looked nothing like the real world coastline, so it just went tundra to tundra i believe. Random spawning of natives throughout it. That always kinda bugged me, i wish it was a little more representative, or at least have the option for it.
So basically any Native American group is game so long as they are actually adding an new NA civ and the alphabet theory thingy.
