North Caucasus
Ciscaucasus was historically covered by the Pontic steppe, mostly on fertile calcareous chernozyom soils, which has been almost completely tilled and grazed. It is bounded by the Sea of Azov on the west, and the Caspian Sea on the east. According to the "Concise Atlas of the World, Second Edition" (2008), the Ciscaucasus region lies on the European side of the "commonly-accepted division" that separates Europe from Asia.
