I noticed the other day that when you travel to earth from another planet, you always come in over South America.

I point this out, b/c in the campaign, Hawthorne says that when she heard of the attack, she came across the ocean looking for survivors. Since we retreat to the Farm and she has some knowledge of the EDZ, one might assume that she came from there. If so, then that means that the ocean she crossed might be the Atlantic.

That got me to thinking that the Traveler/Last city might be in South America, but then i went back and looked at the final cutscene. #1, the Traveler is much to big and would not be obscured by clouds. #2, if you turn the brightness up in photoshop, you can once again see South America. So, either someone at Bungie got lazy with the Earth, or the Traveler is up in Canada. There are some large mountains with Norse names on Baffin Island (Mount Thor, Mount Odin, Mount Asgard).

Another peculiar thing is that there is a new landmass to the east of South America (refer back to the first pic). It's too far north to be the Falklands, and the size and shape do not match. But on Google Earth, it does appear as if the ocean floor might be more shallow in roughly that same location.
