[Portal] How did the outside of Aperture Science change from the end of Portal 1 to the end of Portal 2

In portal 1, when Chell ends up on the floor outside what appears to be the front gate entrance to Aperture Science facilities, and is obviously dragged back down into the labs by Glados, then at the end of Portal 2 when Glados lets Chell go, the door opens and it isn't anywhere near a city or a town like I assume the outside of the lab was at the end of Portal 1, now its in the middle of absolutely nowhere, in a wheat field. How did this happen...? this might be a silly question and be down to the fact that the facility underground could be so big that it stretched all the way into the countryside and into a wheat field, but I'm really stumped on this.

While we aren't given a specific size of the facility, we know the Enrichment Center was built in a mine that extends at least 2500 meters deep, and hundreds of meters in length, and we've no reason to assume it wasn't expanded upon by Aperture or Glados herself.
