Lake Van is a large saline soda lake in eastern Turkey. It occupies a closed basin amid volcanic mountains and has no outlet to the sea.
Soda lake: A highly alkaline lake whose waters contain abundant dissolved sodium carbonate and related salts. Lake Van's carbonate-rich water gives it the alkaline chemistry characteristic of soda lakes.
Nemrut volcano: A large stratovolcano near Lake Van in eastern Turkey, with a caldera containing lakes. Lava flows from Nemrut blocked the basin's former drainage route and helped create Lake Van.
Akdamar Island: An island in Lake Van known for the tenth-century Armenian Church of the Holy Cross. Its shoreline and church make the island a prominent cultural landmark within the lake.
