okay I’m sorry if this has already been posted but now that Half Life 2: Episode 3′s summary has been released (look it up–I can’t link to it or this post won’t show up in the tags, thanks Tumblr), WE NOW HAVE A MORE PRECISE LOCATION FOR APERTURE!!!
Okay, so, we have the Borealis’s drydock here:

We also know that Aperture is located in Michigan’s Upper Peninsula (or UP):

We never knew… until now.

The Borealis’s transportation mechanism had never before been tested. Meaning that, yes, the aforementioned dry dock is indeed the one we see in Portal 2. Which means…

Aperture is somewhere along the southeast coast of the UP.
Now the question is… anyone know if there’s a wheat field around there?
