Lake of Sodom.
The depth is 378m, said to be the deepest hypersaline lake in the world. In a salinity of 33.7%, a harsh environment that no living organism can flourish, otherwise known as the 'Dead Sea'.
The image shows a close-up detail of the banded, crystalline rock-salt strata inside the Sodom Salt Caves, located within Mount Sodom at the southwestern edge of the Dead Sea, Israel.This mountain is unique because it is composed almost entirely of halite (rock salt) covered by a thin layer of cap rock. Over thousands of years, infrequent desert rains have dissolved vertical shafts and carved out elaborate subterranean passages. This geological process has created beautifully layered salt bands that are highly visible to hikers exploring the caves.
