Besh Barmag Mountain outflow of meltwater from the Black Sea to the Mediterranean Sea, rather than a direct incursion of sea water into the Black Sea as a result of global sea level rise. Estimates of the increase in Caspian Sea level height are between + 20 and 30 meters. Besh Barmag Mountain Besh Barmag () literally translated as "Five Finger", is in Siazan District of Azerbaijan, not far from the Caspian Sea. It rises to above the sea level overlooking the Baku-Quba Highway. The mountain is a solid rock and is one of the most famous mountains in the Caucasus, known for
Caspian Sea evaporite sink when cool, wet climates refilled the basin. (Comparable evaporite beds underlie the Mediterranean.) Due to the current inflow of fresh water, the Caspian Sea is a freshwater lake in its northern portions, and is most saline on the Iranian shore, where the catchment basin contributes little flow. Currently, the mean salinity of the Caspian is one third that of Earth's oceans. The Garabogazköl embayment, which dried up when water flow from the main body of the Caspian was blocked in the 1980s but has since been restored, routinely exceeds oceanic salinity by a factor of 10.
