On closer inspection, at the approximate location where one would find it in-game is a wide open area the size of the other big cities but with simple pine trees plopped symmetrically into the ground (this is on top of a high mountain and you can't get there without TCL in console, but it's still within the invisible border of the land so you don't have to disable border regions)
Also, the area doesn't look nearly as "prepared" as the rest of the surrounding area (there is only 1 ground texture, no rocks, only trees) and there is an "interrupted" dirt-road texture going up the side of the mountain to this location, though covered in big rocks. The road passes by an unpopulated watchtower with no map marker on the way up the mountainside.
...It almost looks as if it was there, but got eaten.
What ever could have eaten an entire city? Deadline day?
