The Caspian Sea: The world's largest inland body

The Caspian Sea Basin lies as low as 132 meters below sea level. The forested slopes of the Caucasus mountains and Iran's Eburz mountains abut against the southwestern and southern shore. To the east are the Balhhan Ramges and the Kara-Kum desert. To the north is the Ust-Urt plateau and beyond that are the rolling Volga uplands.
