The Taschksee , also Täschksee or Tashk-See ( Persian دریاچه طشک Daryātsche-ye Tashk ) is a salt lake in the province of Fars in the southern Zāgros Mountains of Iran , in the midst of large mountain ranges up to 2500 m above sea level . It is located immediately north of Lake Bakhtegan , about 80 km east of Shiraz . Together the lakes (picture) are also called Neyriz lakes. The lakes are usually separated by a small strip of land, but in wetter times they unite. They lie in a desert-like landscape at an altitude of 1525 m.
Over millions of years the rain has washed minerals from the surrounding rock and carried them into Lake Tashk. After long periods of drought, the drainless lake dries up and leaves the crystallized salt in the bank area. This creates the high salt content and a fantastic play of colors in complex patterns. The region is economically interesting due to its high occurrence of zinc blende . But the true beauty of Iran's mountain desert is only revealed when you look from space: The salt lake presents itself like a large cut diamond with a ring-shaped structure.
Lake Tashk is fed by the overflow of the swamps in the west and by the water of a large spring in the northeast.
Thousands of water birds gather year after year on their long routes at the lake, which is part of the Bakhtegan National Park .
Salt lake excursion
Permanent or temporary lakes - so-called salt lakes or playas - form in dry mountain valleys or intramontane pools. Such lakes are therefore the site of formation of sometimes very unusual evaporite minerals , e.g. soda ( sodium carbonate ) or borax (sodium borate) and other salts. The water of such playas can react extremely alkaline ; As drinking water, due to its high salt content, it is inedible, harmful to health or even poisonous.
