@Wiibomb This page includes some info along with the maps http://monsterhunter.wikia.com/wiki/World_of_Monster_Hunter take note the Heavenly mountains is said to be in Siki Country and the Desert in 4U is the same as the Old Desert just terrain changed a bit over the years. Also every area actally has a actual name like the "Old Desert/Dunes" is actually called in MH the "Dede Desert".

Most of the info still is not translated into english as well. http://wikiwiki.jp/nenaiko/?%C0%A4%B3%A6%B4%D1

Considering most of MH stuff is in japanese including the info books and such.
