It has been scientifically proven that holidays in local climatic zone much more useful than going to distant countries. This is especially true for people with health problems, the elderly, families with small children, and pregnant women. One of the famous and well-established vacation spots are the salt lakes of the Orenburg region. Reviews about the resort are positive: tourists note the healing effect of the reservoirs located here. We will talk about them today.
Healing lakes of the Orenburg region
Traveling through the expanses of our vast Motherland, getting to know it and receiving aesthetic pleasure from contact with nature, you can find yourself on the shore of a salt lake. In Russia there are a large number of, and they all have unique medicinal properties. They are also called mineral lakes for their high content of microelements and antiseptic properties, and the mud of such a reservoir has a natural healing effect. To benefit from the ultraviolet rays reflected from and become the owner of a natural, beautiful tan, you must definitely visit it! The main “folk hospital” that Orenburg is proud of is salt Lake. Reviews from numerous tourists prove that here you can not only relax, but also receive treatment.
From time immemorial
Water and mud therapy came to us from ancient times. Even then, healing mud and mineral water were used to get rid of diseases and heal wounds. They treated skin, gynecological and many other ailments. Such a terrible disease as psoriasis can be cured by swimming in such a body of water. Banal but annoying boils, acne and other skin defects disappear almost without a trace after taking such salty baths. Tourists appreciate the opportunity to improve their health and get a real “kiss of the sun.” It is not without reason that it is believed that the main attraction of which Orenburg is proud is the salt lakes. Treatment is combined with a pleasant pastime, which makes ponds especially tempting.
Where do salt lakes come from?
According to scientists, such reservoirs appear in arid places, in the crater of which there is no drainage. The water that rivers bring there only flows into them, but does not flow out. When liquid evaporates from a reservoir, the salt remains at its bottom. This is how salt lakes are formed.
You can find such a lake in any corner of the country. The Salt Lakes are rich in healing waters and have miraculous powers, and everyone knows the benefits of swimming in them.
A unique geological object is Lake Razval in the Sol-Iletsk region, located at the mining site. It is the deepest among its peers and quite large, because its area occupies 10 hectares. Its origin is interesting. The lake appeared in 1906, when a spring flood flooded a salt quarry. In the central part of the Iletsk salt dome there was a reservoir 240 meters wide, 300 meters long and 20.5 meters deep. This is analog Dead Sea, since it is 305 g/l. That's why some of the main attractions it's proud of Orenburg region, - salt lakes.
The Iletsk salt dome was formed in the second half of the 18th century. This is the result of rock salt mining and karst processes in its thickness. Then the quarry connected with the Peschanka River. At the same time, a salt lake called Razval was formed. The water in it has a high concentration of salt - 260 g/l. Therefore, brine does not freeze even at -20 in water and -40 degrees in air. This lake is also unique in that there is permafrost at its bottom. The high density of water allows a person to lie on the surface without moving.
Just 70 km from the Iletsk rock salt deposit is the city of Orenburg. Salt Lake Razval is of regional importance and is included in the main list of protected sites.
Benefit for health
The ancient doctors Hippocrates and Avicenna spoke about the benefits of swimming in salt waters. Despite the fact that the latter came from Central Asia, on whose territory there are no such lakes, the doctor appreciated the properties of salt water. The city of Orenburg welcomes a large number of tourists wanting to receive treatment. The salt lake Razval is distinguished by its healing effect, which it has on all organs and systems of the human body. Due to the high content of bromine salts, chlorine and other trace elements in water, it helps in the treatment of rheumatism, osteochondrosis, bronchial asthma and many other diseases.
It must be remembered that swimming in salt lakes should be moderate. And you need to alternate it with sunbathing. It is recommended to bathe regularly for 7-10 days.
Lake Tuzluchnoe
Medicinal products have ancient origins. Even nomadic tribes made halts on their banks, using mineral waters and therapeutic mud for healing the whole body. Such reservoirs include the salt lake Tuzluchnoye, recognized as the oldest surviving reservoir of the Sol-Iletsk salt dome. Its area is 24 thousand square meters. m, the depth reaches 4 meters. The Orenburg region is proud of it. The salt lakes of this region are widely studied in the laboratories of the testing center. There they found that, according to their physical and chemical indicators, silt deposits belong to highly mineralized medicinal mud. They have high thermal properties. In addition, they are very flexible. Contains a large amount of water-soluble salts, as well as iron, bromine and boric acid.
The healing mud of Lake Tuzluchnoye is black or dark gray. It relieves spasms as it has a relaxing effect. It has a regenerating, anti-inflammatory, antiseptic effect and enhances the viability of cells throughout the body. Positive properties mud is due to the fact that it contains a large number of biologically active substances that can influence energy processes and suppress the development of pathogenic organisms.
Pond Dunino
Rich in medicinal reservoirs, salt lakes are represented by another medicinal object. This is the Dunino reservoir, which, due to the bromine content in it, is called bromine. It was formed in 1896, and is located just 50 meters from Lake Razval.
Lake Dunino stretches along 88 thousand square meters from west to east. m, its depth is 4 meters. A distinctive feature of the reservoir is its reddish color. The crustacean Artemia gives it a beautiful hue. There is a large amount of it in the reservoir, and in the summer it actively reproduces.
The healing mud of Lake Dunino, green or brown in color, is located at the bottom. Its temperature in summer rises to +50 degrees, which improves its healing properties. During the summer period, crustaceans reproduce 3-4 times, they synthesize organic substances, which, when they die, form healing mud. If you scoop up water from the lake, you can see small living creatures of a reddish color. These are the same crustaceans thanks to which the mud from the bottom of the lake becomes healing. “Tsvetnoy” and other reservoirs attract thousands of tourists to the Orenburg region. Salt lakes will not only help improve the health of vacationers, but will also contribute to mental relaxation.
Resort infrastructure
The city is built in such a way that everything a tourist needs is in close proximity. The station is located a five-minute walk from busy areas, and you can easily resolve the issue of accommodation right there. Owners of private houses and apartments offer their services. Those who come to the resort town by personal transport will not have any questions about how to get to the salt lake. A continuous flow of cars will indicate the exact path to the desired location. In all travel agencies in the country you can easily purchase a ticket to the domestic analogue of the Dead Sea.
Note to tourists
Like any resort town, Sol-Iletsk offers vacationers a rich cultural program. On every corner, tourists are beckoned by the alluring smell of kebab shops, cafes of Russian and oriental cuisine, in which, in addition to wide choice dishes, homemade wines are offered. In the evening, numerous bars offer everyone a great rest and good time for the soul. For those who like a quiet pastime, there are numerous parks, public gardens, and a local history museum.
Now you know that the main pearl that the Orenburg region is proud of is the salt lake. The city will gladly welcome everyone, saving them from unnecessary hassle with finding housing and organizing meals. Experienced doctors will select an individual recovery course and provide all the necessary medical and advisory assistance.
On native soil
There is an opinion that the recreation industry in Russia is practically undeveloped, and in order to spend a vacation in comfort, you need to go to other countries. We are able to improve the situation on our own: when we come to domestic resorts, we invest our money in the development of local tourism. Relax in Russia, and high level service will not keep you waiting long!
The Dead Sea is famous for its unusually high salt content, although in fact this body of water ranks only as the fourth saltiest sea and lake in the world.
Seas and oceans are traditionally considered to be the saltiest bodies of water. And this is mostly true. Water covers more than two-thirds of our planet's surface, and 96% of it is in the oceans. Ocean waters contain thousands of billions of tons of dissolved salt.
The salinity of water varies at different points in the oceans. Around the poles, the constant presence of snow and ice reduces salt levels, while closer to the equator more water evaporates from the surface of the seas, meaning higher salt levels in the water.
But there are bodies of water on our planet where there is much more salt than in the seas and oceans.
Dead Sea
The most famous such body of water is the Dead Sea, located on the border of Jordan and Israel. The water here is 10 times saltier than the average sea water. However, the Dead Sea is far from the saltiest sea. It ranks only fifth among the saltiest bodies of water on Earth.
In addition, the Dead Sea is not a sea at all. Although the term "sea" is used quite loosely, it essentially refers to a large body of salt water that is partially surrounded by land. The Dead Sea is completely surrounded by land and has no access to the ocean or open sea. In fact, it is a lake, but it is large and salty, which causes confusion.
The shore rocks of the lake sparkle with crystallized table salt in places where the sun causes the water to quickly evaporate. In addition, the Dead Sea is the deepest hypersaline body of water in the world. Its depth reaches 330 meters.
IN last years this body of water rapidly decreased in size, to the point that rumors arose about its complete disappearance. However, Israeli geologists now claim that it will stabilize at current levels in the near future.
Lake Don Juan
Despite its celebrity status, the Dead Sea cannot take away the laurels of the saltiest body of water from a tiny lake called Don Juan. This baby does not exceed 300 meters in length and 100 meters in width, and its depth is 10 centimeters. However, the percentage of salt content in the lake is 44%, which is 10% more than in the Dead Sea and 40% more than in the ocean.
The lake is located in Antarctica, in the McMurdo Dry Valley, famous theme that it is the driest place on the planet - there is no precipitation, and strong winds prevent glaciers from forming on the interior of the mountains surrounding the valley.
Source of salt
Scientists do not know the exact reason for such a high salt content in the lake water. Perhaps this is due to the fact that it is completely cut off from other bodies of water and is not diluted fresh water coming from precipitation and melting glaciers. All the salt contained in the waters of Don Juan cannot leave them. All she can do is freeze or evaporate.
With such a high percentage of salinity, the lake almost never freezes - this requires a temperature below -53 degrees Celsius. All that remains is evaporation. The water evaporates, resulting in an even higher percentage of salinity.
While other saltwater bodies of Antarctica obtain fresh water from snow and ice, Don Juan always remains undiluted. Scientists are still trying to find the source of salt in the waters of the lake.
Salt on land
It is noteworthy that reservoirs are far from the saltiest places on the planet. Record accumulations of this mineral are found on land.
The Uyuni Salar is the largest in the world, its area exceeds ten thousand square kilometers. It is located in Bolivia and is actually the bottom of a dry prehistoric salt lake.
The basin of this lake is unusually flat; geologists noticed a difference in height of only one meter. Today this huge flat valley is covered in sparkling salt crystals.
During the rainy season, tourists flock to Uyuni to see the world's largest mirror surface, and flamingos come here to lay eggs, perching on large salt marshes.
Salt has been mined in the vast expanses of Uyuni for several centuries, but there is still so much of it that it will last for a long time.
Underground springs
Although the largest deposit of salt is in Bolivia, the largest exporters of this mineral are Australia and China. The most productive salt mines are located there.
However, the largest salt mine is located in Canada. Its depth reaches 550 meters, and its area is seven square kilometers. Seven million tons of salt are extracted from the mine every year. This place is near the Great Lakes, and geologists assume that the salt deposits there are very rich and lie at comparatively great depths, covering a huge area. This wealth is left over from a prehistoric sea that dried up about 420 million years ago.
The fact that it is difficult for scientists to name the single saltiest place on Earth tells us that there is still much to be learned from the history and depths of our amazing planet not studied and kept secret. It is quite possible that there is another body of water in the wilds of the Siberian forests, which will turn out to be saltier than the lake Don Juan.
Salt lakes on our planet are not uncommon, although many people think that there are much more freshwater ones. These bodies of water may look like small seas or like very modest ponds, but size is not the main thing here. Each has its own unique ecosystem, and each has its own mystery. You can admire them, you can get the necessary substances from them, they will help improve your health and tell you about the past of the Earth. So, we present the TOP 9 amazing salt lakes.
Where do they come from? As a rule, the concentration of salt in closed reservoirs increases gradually as the water evaporates. In this case, both rocks and groundwater can be a source of salts, but the main factor is a decrease in volume. This process can take millennia, but human intervention speeds it up significantly. Example - Aral Sea. If water is actively used by people for various needs, and its inflow decreases, then an ordinary lake can dry up and become salty in a few decades. The water in it is no longer suitable for drinking or irrigating fields. Lake salinization is one of the pressing problems associated with global water resource shortages.
Underwater salt lakes on the ocean floor (there are such!) arose differently. Millions of years ago, the seas dried up, and in their place a very thick layer of salts formed. And then the water returned, and at the greatest depth a “brine” appeared, which, due to its high density, did not mix with the waters of the returning ocean.
Salt lakes also form in the craters of volcanoes.
The salinity of lakes is measured in ppm: this value reflects how many grams of salt are contained in one liter of water. For example, for the Red Sea this figure is approximately 40, for Gulf of Finland- 2, and for the Dead Sea - about 300.
What's all the salt? People have used mineral lakes since ancient times. Firstly, the habit of salting food forced us to look for new sources of the main seasoning. Secondly, swimming in salt water turned out to be beneficial for health, and the deposits of healing clay along the shores of lakes are an excellent cosmetic product. In addition, various substances necessary for medicine and industry can be extracted from salt water. Of great interest from the point of view of biotechnology are unique extreme bacteria that live calmly even in very salty water. They can be used to extract metals from ores, or to treat wastewater.
1. Urmia (Iran). This lake was once the largest in the Middle East. However, in Lately it is becoming smaller and smaller - photographs taken from space make it possible to observe this. Unreasonable consumption of water from rivers for irrigation has led to the fact that over 40 years the reservoir has shrunk by 70%. The water there usually has a pinkish tint due to the proliferation of Dunaliella algae. After the winter and spring rains, Urmia turns blue again. At the same time, the salinity of the water drops from 260 to 150-80 ppm. There are more than a hundred islands in the lake, some of which are covered with pistachio forests. Pelicans and flamingos nest here. If the Iranian government does not implement a program to save Urmia, the lake will dry up completely and 10 billion tons of salt will remain in its place, scientists warn.
2. Dead Sea (Israel, Palestine, Jordan). One of the most famous salt lakes in the world. Its length is 50 km, maximum width is 18 km. The main feature of this reservoir is that it is located at the lowest point of land on the planet - more than 400 meters below sea level. The main source of water in the lake is the Jordan River.
This is one of the first health resorts in the history of mankind. Also, since ancient times, potassium carbonate (potash) was mined here to fertilize the soil. The Dead Sea was called the Asphalt Sea, and this is no coincidence: natural asphalt is formed at depth, which the ancient Egyptians used to mummify the bodies of the dead.
Environmentalists are concerned that the water level in the Dead Sea is falling by an average of 1 meter per year. This is due to the active use of groundwater, the extraction of minerals through evaporation and climate change.
3. Lonar (India). Located in a crater that appeared in basalt rock after a meteorite fell - this is the only such crater on Earth. The name “Lonar” is simply translated as “salt lake”.
The lake is both salty and alkaline. The salinity of the water in it is 10.7 g/l. The diameter of the lake is 1 km, and the depth is more than 130 m. The water is muddy green and has a rotten smell, so it is not very pleasant to be on the shore.
Since 1842, commercial salt mining has been carried out on the lake. There were five or six types of Lonar salt on sale, varying in composition and color. Nowadays it is only used local residents. A rare mineral, geylussite, was discovered in Lake Lonar - these transparent crystals resemble crystal.
4. Baskunchak (Russia). Is in Astrakhan region. The area of the lake is approximately 106 square meters. km, salinity is about 300 g/l.
Basically, the lake is fed by underground sources. Salt mining has been carried out here since the 8th century. Baskunchakskaya was built especially for its removal. Railway from the lake to the Vladimirovskaya pier on the Volga. Today, from the lake, 1.5 to 5 million tons of NaCl are obtained annually.
Above the surface of the lake you can see mysterious pillars covered with a salt crust. They remain from the footbridges along which, even before the 1917 revolution, workers walked to collect salt. The Baskunchak sanatorium, which is located on the shore, is very popular among tourists. Salt solution and mud baths help cure many diseases.
5. Great Salt Lake (USA). Located in Utah, it is the largest salt lake in the Western Hemisphere. The salinity of the lake also varies depending on the water level, ranging from 137 to 300 ppm.
The Great Salt Lake is also known for regularly causing heavy snowfalls. There are no miracles here. It’s just that in winter the water in the lake is much warmer than the air above it, which leads to the formation of clouds and precipitation. Oolitic sand can be seen on the shores of the Great Salt Lake. It consists of round or spherical mineral formations resembling very small pearls.
The lake is divided into two parts by a dam along which trains run. The southern and northern parts have different salinity and, as a result, different colors due to the distribution of different types of algae. In 1970, the installation “Spiral Dam”, created by American artist Robert Smithson, appeared on the shore of the lake. The object is visible only when the water level in the lake drops to 1280 m above sea level.
There are many legends about the lake. For example, they say that in 1875 two whales were released into the reservoir in order to attract more tourists. Since then, no one has ever seen whales. Another story is connected with the local Nessie - the Monster North coast, who once allegedly attacked workers.
6. Don Juan (Antarctica). This small body of water owes its name not to the famous hero-lover, but to two helicopter pilots. Their names were Don Ro and John Hickey, and in 1961 they flew over the lake and noticed that the water in it did not freeze, despite the 30-degree frost. It later turned out that the lake’s salinity is so high that it is not covered with ice even at minus 53 degrees! The salt content in Don Juan is more than 400 grams per liter. The source of water in the lake is melting glaciers. The surface area of the reservoir is only 0.3 km. No signs of life were found in the lake. Experts note that conditions in this area resemble those on Mars.
7. Assal (Djibouti, East Africa). One of the saltiest lakes on the planet (up to 400 grams per liter) is located in the crater extinct volcano. This is the most low point Africa. The length of the reservoir is 19 km, width is 6.5 km. During the day, the water in the lake strangely changes its hue, up to fluorescent colors. Salt is mined on an industrial scale, while nomads evaporate it in the old fashioned way on the shores of the lake and send it to Ethiopia on camels.
8. Socompa (Argentina, Chile). The lake is located on the border of two states, in the Argentine Andes, at an altitude of 3600 meters above sea level. There was a time when this body of water was considered exclusively as a source of lithium, without which it would be impossible, for example, to produce batteries. This metal was obtained by evaporating a brine solution in the sun. However, now Socompa and other Andean salt lakes are becoming specially protected natural objects. The reason is that scientists discovered stromatolites in the water - “layered” structures formed by minerals and cyanobacteria. These are the most ancient ecosystems on Earth. Some of the finds are several billion years old, and they can help scientists learn more about the origin of life on our planet.
9. Underwater salt lakes (Gulf of Mexico). The saltier the water, the higher its density - therefore, numerous lakes at the bottom of the bay have very clear boundaries. The water in salt pools is 4-5 times saltier than ocean water. If a submarine descends towards such a body of water, it begins to slide along its surface. Underwater lakes range in length from 1 m to 20 km. As a rule, they have a high concentration of methane, and only extremophiles - living creatures adapted to harsh conditions - can live in them. For example, bacteria and mussels, tube worms and shrimp. Scientists believe that such creatures could easily survive on other planets.
