Fake map north should be pointing away from Antarctica dumbass. Read a book.

That outline is like the entire continental shelf, or all the area where the glaciers are directly over rock (as opposed to having ocean in between), or something like that.

Might actually be smaller than Australia if the ice were gone, give or take things like sea level rise and isostatic rebound.
