'Lake Baskunchak' () is a
salt lake of 115 km² in
Astrakhan Oblast,
Russia, located at , about 270 km north of the
Caspian Sea, and 53 km east of the
Volga. Since 1997 the area is strictly protected as
nature reserve.
The surface elevation of the lake is 21 m below
sea level. It is fed by a river that draws from an area of 11,000 km². The
salinity of the lake is about 300 g/l. Since the
8th century its salt was mined and distributed via the
Silk Road. Nowadays the lake's salt of distinct purity (99.8 %
NaCl) covers 80 % of
Russia's salt production. Depending on need, about 1.5 million to 5 million tons of salt are mined per year.
To the south of the lake ''Mount Bolshoye Bogdo'' rises to 150 m above
sea level, forming the highest elevation in the
Caspian Depression. The hill is pushed up about 1 mm per year by a
salt dome.
Sinkholes, and
Karst caves of up to 1.5 km length lead through the hill. It also is the only area in
Europe where
Triassic lagerstätten surface. To the local
Kalmyk people, it is a holy hill.
