Because quite a few things from other games have been retconned into this game. XD Plus, the whole code system for areas on the map seriously implies that they made some area named B7R. It wouldn't have to be mountainous.

Since J4E is in Japan and B9K is in the Bahamas, B7R would have to be in another country that starts with "B".
