What is the approximate age of Baikal. We arrive and settle down. Shores of Lake Baikal

Lake Baikal for the majority is somewhere very far away. Origin Lake Baikal shrouded in legends about great catastrophes on a planetary scale, about the gods and their deeds. The scientific point of view also exists - there is no mysticism in it, of course.

Lake Baikal is located on the territory of the Irkutsk region and Buryatia. Considered a lake tectonic origin. The age of Baikal is estimated differently. Some scientists put 35 million years. But the doctor of geological and mineralogical sciences A.V. Tatarinov in 2009 put forward a version that the deep-water part of Lake Baikal was formed 150 thousand years ago, and the modern coastline and at all - only 8 thousand years. Tatarinov substantiated such results with the results of the Mirs expedition to Baikal. So, with the age of Lake Baikal, everything is also very ambiguous.

Lake Baikal is also called Siberian Sea.

Lake Baikal contains 19% of all world reserves fresh water. How much water is in Lake Baikal is estimated at 23,615 km³. There is only one lake in the world, the displacement of which is greater than in Baikal - the Caspian Sea (not everyone knows, but there is a lake along this sea).

Despite the fact that Baikal is located in, there is a lot of sun here. The climatic conditions on Lake Baikal have their own unique features: either the sun is mercilessly hot, but cold winds blow, then fierce storms fly in, then calm and hot weather sets in in summer and tens of thousands of tourists flock to Lake Baikal for a beach holiday. In count sunny days Lake Baikal surpasses many resorts of the Black Sea and Mediterranean coast.

Max Depth Lake Baikal - 1642 m. Many people write that Lake Baikal is shaped like a crescent moon. Rather, sorry if something is wrong - a banana. But very big. The length of Baikal is 620 km (as from Moscow to St. Petersburg approximately), the width reaches 80 km. The length of the coastline is 2100 km.

Lake Baikal has 27 islands, the largest of them. Many islands are sacred to the locals and protected by law. In general, there are many sacred places on Baikal, the history of which is shrouded in mystery and legends. The predominant religion here is rather Buddhism, at least Buddhist symbols and objects of worship are found everywhere.

Lake Baikal water

The water temperature in Baikal is a phenomenon. In summer, only the upper layer of water and shallow coastal bays warm up in the lake. But at a depth the temperature is always constant - about +4 ° C.

The waters of Lake Baikal are a separate mystery. Lakes of this age do not have such crystal clear water, and in Baikal it is very clean. Usually, over time, lakes silt up, and after 10-15 thousand years, swamps are already in their place. Baikal not only does not grow shallow, but also contains clean water, which you can drink directly from the lake without fear. In addition, the water of Lake Baikal is saturated with oxygen to a very high degree in comparison with other freshwater reservoirs.

Lake Baikal owes its purity to a small (1.5 mm long) crustacean called epishura. There are a lot of these crustaceans in the water of the lake. They clean the water and are food for the famous Baikal omul and predatory invertebrates.

The transparency of water in Baikal is also very high. IN good weather through the 40-meter water column you can see the bottom of the lake! In winter, Baikal also has surprisingly transparent ice. You just need to find a place that is not swept up by snow, and so to speak - feel like God - walk on the water. The water above is really frozen, but below it is the same picture - the bottom, fish, and you are walking above them.

Baikal is fed by the waters of more than 300 rivers, and only one river flows out of Baikal -.

Baikal ice

Lake Baikal does not freeze evenly in winter. Bays and bays, as well as Northern part The lake freezes in November-December. And in the south, ice rises only in February, and if the winter is warm, then even at the end of February.

The thickness of the ice on Baikal by the end of winter reaches 1 m, and in the bays - 1.5–2 m. There is a phenomenon on Baikal that the locals call "stanovye cracks". This is when cracks appear in the ice in severe frost. They break the ice apart large fields. The length of these cracks is amazing - from 10 to 30 km, and the width is only 2-3 m. As you understand, it is better not to be in such a place at the time of the break. Breaks occur every year and in approximately the same places of the lake. The sound effect is similar to gun shots.

Such gaps save the fish in the lake from lack of oxygen. Here is such a mysterious, but necessary natural mechanism for the lake. And due to the transparency of ice, it penetrates through it sunlight, thanks to which planktonic algae that release oxygen in the water develop rapidly even in winter.

Another amazing phenomenon with ice on Baikal is ice hills. These are hollow cone-shaped ice hills that reach a height of 5-6 meters. In some of them you can find the "entrance", and it is usually located in the direction opposite to the shore. Such an ice tent turns out. Sometimes such tents stand alone, but are often grouped, reminiscent of mountain ranges, only in miniature.

Another one mysterious phenomenon was discovered with the help of satellite imagery - dark rings.

The rings have a diameter of up to 7 km. Scientists came to the conclusion that the rings are formed due to the rise of water from the depths of the lake. Due to the temperature difference, a clockwise flow occurs, reaching different velocities in individual zones. As a result, the ice cover is destroyed, and the shape of the destroyed areas is ring-shaped.

Shores of Lake Baikal

The landscape of the coast is very diverse. The largest part is occupied by the taiga, in some places it is swampy. There are many hard-to-pass places where there are neither roads nor settlements. But there are many such areas that look quite hospitable, sand, pines, cedars, wild rosemary. But from the side of the Tazheran steppe, in the vicinity and on the island, the landscapes of the Baikal region are different - steppes, rocks with woodlands Siberian larch.

The terrain on the coast of Lake Baikal is generally mountainous and transport infrastructure because of this, he suffers greatly. Many places to drive on road transport from one settlement located on the coast to another located, you need to make a big detour of tens of kilometers. A quarter of the coast of Lake Baikal has no public roads at all and is practically uninhabited (there are places for the Chinese to settle, I think they are happy).

Bottom relief

Lake Baikal is unique in terms of bottom topography. It has its own underwater mountain ranges, the largest of which are Akademichesky and Selenginsky. These ridges divide the lake into three basins.

Earthquakes are not excluded on Baikal. More precisely, this is a common thing. But tremors usually do not exceed 2 points. But there were other cases:

• in 1862, an earthquake of 10 points was recorded, as a result of which a land area in the northern part of the Selenga delta went under water
• there were points about 9 points in 1903, 1950, 1957 and 1959
• in 2008 - 9 points
• in 2010 - 6 points

Fauna and flora of Baikal

vegetable and animal world are unique here. The lake serves as a safe haven for almost three thousand species of animals and thousands of plants. Many species are found only here. And this despite the fact that, as scientists suggest, more than 20% of the living organisms living in the lake are still unknown to science. Fishing lovers will be fine on Baikal (if the bite goes, of course). Grayling, taimen, whitefish, sturgeon, omul, lenok, golomyanka are common. There are about sixty species in total.

The top of the biosphere on Lake Baikal is occupied by the Baikal seal. There are no other mammals in this reservoir. Until now, there are heated debates about how the Baikal seal got to Baikal and comfortably settled down here - especially marine mammal. It is assumed that she came here in ancient times. ice age, moving from Arctic Ocean along the Angara and the Yenisei. Now tens of thousands of animals live here.

Many animals and birds also live along the shores of Lake Baikal. Here you will meet gulls, goldeneye, there are shelducks, mergansers, white-tailed eagles, and other birds. You can see the mass bathing of brown bears (just be careful!). Musk deer, the smallest deer on Earth, lives in the mountainous part of the Baikal taiga.

Where does the name Baikal come from?

Researchers are still arguing about the origin of the name of the lake. Several guesses:

• Bai-Kul - translated from Turkic means "rich lake";
• Baigal - from the Mongolian "rich fire";
• Baigal Dalai - in the same Mongolian means "big lake";
• Beihai - in Chinese means "North Sea";
• Baigal-Nuur - Buryat name;
• Lamu - this is what the Evenki called the lake.

It is believed that the first explorers, who appeared here in the seventeenth century, eventually adopted the Buryat name, but softened the letter “g”, giving the name the current sound.

Tourism and recreation on Lake Baikal

There are a lot of beautiful places on Baikal. On my site you will find many stories of our tourists about trips and holidays on Baikal (see the section "Stories"). A feature of tourism on Baikal is that the places you would like to see are often located at great distances from each other. So if you want to see not everything, but many of the beauties of Lake Baikal, you need to work out a competent route. If you feel that you can’t do it yourself, contact private guides or buy a comprehensive tour to Baikal.

In any case, you will not be able to see everything on Baikal at one time. Baikal is large, to go around it all you will need more than one vacation.

The most massive tourist visit to Lake Baikal takes place, of course. in summer. The most popular places are the village of Listvyanka, the Small Sea and Olkhon Island. People with a small budget, and even the most demanding, will find a place for themselves. Lake Baikal is visited not only by Russians, but by many tourists from all over the world. The latter, moreover, sometimes give fabulous money for such a vacation, but they still go.

In general, judging by the reviews, holidays on Lake Baikal are not among the cheapest, especially if you need to travel from other than nearby cities. Nevertheless, Baikal sets attendance records - the number of tourists is estimated at seven figures per year.

In summer, people relax on the beaches, go on bicycle and car tours, and go hiking along the coast. There are rafting on the rivers flowing into Baikal, and much more.

Climbing cliffs, mountains and descents into grottoes and caves are popular in all seasons.

Fishing

There are a lot of fish in Baikal and lovers find a variety of places in the hope of catching omul or other fish on their own. For the most gambling, there are specialized bases with different levels of comfort. Fishing is done on rented boats.

The most popular places for fishing on Baikal are Chivyrkuisky Bay, Mukhor Bay, shallow bays of the Small Sea and, of course, rivers flowing into the lake.

Lake Baikal in winter

Despite the harshness of the Siberian climate, there are people who like to come to Lake Baikal in winter. Fantastic ice world Baikal is mesmerizing. Snowmobiling is popular dog sledding.

Most Popular Attractions

Many historical and architectural sights, even more monuments of nature and culture are concentrated on Baikal.

One of the most famous attractions is shaman stone. This is a pair of boulders rising above the water at the source of the Angara. Locals have been worshiping these stones since time immemorial and consider them endowed with special powers.

Another rock, the photo of which is unusually distributed on the Internet at the request of "Baikal" and "Olkhon Island" - Rock Shamanka. Also sacred place for the Buryats, access here for tourists was not always open.

Also on the island of Olkhon there are many other cult and historical sites. Olkhon is good because in the summer you can sunbathe there, swim, and visit a bunch of excursions or travel around the island on your own.

Holiday seasons on Baikal

Baikal is beautiful in all seasons. Summer, as well as throughout Russia, is the most popular season. The warmest from the second half of July to the beginning of August. Since November, it has become not very hospitable here, until the ice rises. In March and early April, tourists flock to Lake Baikal, especially those who like to take photos. The reason for this is the sparkling, transparent ice of Baikal. There is another one - ice fishing. In the spring, Baikal is also very beautiful, there are no more severe frosts and winds. Winter lovers find a combination weather conditions and the beauty of the scenery is very attractive.

Relax on Baikal, enjoy its nature and energy. Take care of Lake Baikal, do not leave dumps behind you, do not arrange logging. This lake is thousands of years old, and after many, many years, it needs to be as beautiful and attractive as it is now.

Baikal is one of the wonders of Russia. The depth of Lake Baikal is a record. The African Lake Tanganyika, which follows it, has a depth that is 200 meters less. The reservoir is popular with tourists and explorers. Until now, the secrets of Baikal have not been fully disclosed and excite scientists.

Where is

Located almost in the center of Eurasia, in Western Siberia, on the border of the Irkutsk region and the Buryat Republic, Baikal has the shape of a huge crescent. In terms of area, it is equivalent to the Netherlands, Belgium or Denmark. Surrounded by mountains and hills, the reservoir occupies a huge pit. The question of how deep Lake Baikal is is very interesting. We will tell about this later, and now we will describe the relief of the coast. In the eastern part it is relatively flat, the mountains are tens of kilometers away. West Bank lakes are mountainous.

The Baikal area is seismically active. Earthquakes of small magnitude occur regularly, and there are strong ones, the echoes of which are felt even in Irkutsk. So, in the second half of the 19th century, an earthquake with a force of 10 points occurred. As a result, a land plot of 200 square meters was flooded. km, where 1300 people lived. Strong tremors were noted in 1959 (9 points), in 2008 (9 points) and 2010 (6 points).

The history of the lake and the name

For a long time it was believed that the age of Baikal is 25-30 million years. But recent studies of the relief of the bottom of the lake with its mud volcanoes have shown that it is up to 150 thousand years old. In this regard, Baikal is also unique, because the average age of lakes of a similar origin is 10-15 thousand years.

The rift basin in which Baikal is located is similar in structure to the Dead Sea. Its depth is the depth of Baikal. The opinions of scientists on the formation of the basin differ.

There are 3 versions:

1. The depression is the result of a transform fault.
2. The depression arose as a result of the action of a hot mantle flow under the lake.
3. The depression was formed as a result of minor collisions of Hindustan and the Eurasian plate.

Obviously, as a result of seismic activity, the relief of the bottom of Lake Baikal is changing and is still subsiding.

The origin of the name of the lake is unclear, but all four points of view reflect the greatness of the reservoir and indirectly indicate how deep Baikal is: Japanese - "great water", Turkic - "rich lake", Mongolian - "rich fire" and Chinese - "northern sea" . In our country modern name began to be used in the 17th century, it was borrowed from the Buryats (Beigkhel): in Russian the word was assimilated and the usual pronunciation was established - Baikal.

Features of the landscape and climate

The record depth of Baikal and the vast area of ​​the watershed determine the local climate. Mild winters, but rather cool summers, long autumns and long springs - these are the climatic characteristics of the areas adjacent to the lake. Also, the weather of Lake Baikal is affected by local specific winds, such as barguzin or kultuk. Because of the current winds, Baikal is referred to as the most restless lakes in the world.

Another remarkable property of the climate is mirages, which appear up to 7 times a year and last for 5-6 hours. They arise due to the difference in air temperature between the surface of the water and the space above it. Mirages occur due to the refraction of rays. Landscape objects can visually rise above the water surface so that the horizon is visible. Another kind of mirage is when thousands of kilometers distant natural objects approach optically.

Baikal waters: features and currents

Since ancient times, the water of the lake has fascinated the locals: they idolized it, they treated it. It is saturated with oxygen, close in composition to distilled water, and due to the action of microorganisms, it is practically devoid of minerals. The volume of Baikal water is 90% of Russia's fresh water reserves and 20% of the world's. For comparison: there is more water in our great lake than in the 5 largest American lakes combined.

Surprising transparency Baikal water: Visibility reaches 40 meters. True, this figure can drop to 10 meters during the flowering period of plants. Depending on the time of year and the activity of plants and microorganisms, Baikal water changes its color from bright blue in cold weather to green in summer and autumn.

Baikal is saturated with 336 rivers and streams constantly flowing into it. Turka, Snezhnaya, Upper Angara, Sarma are the largest of them. The Angara is the only river flowing from Lake Baikal.

Depth indicators

How deep is Lake Baikal? It is determined by the origin and parameters of the depression in which the lake is located. The last depth studies were carried out in 1983, they were confirmed in 2002. The lake is fascinating: with an average of 730 meters, the maximum depth of Baikal is 1630 meters. There are two more lakes on Earth with a depth of more than 1000 meters: Tanganyika and the Caspian Sea. And in last water salty, not fresh. Even average depth Baikal is amazing - few lakes on Earth can boast a value of 730 meters.

Currents act on the surface of Lake Baikal, encircling its shores and largest islands. In certain places (the western coast of the Small Sea), the current is quite strong, so even in calm weather, ships drift. The decrease in the intensity of water movement is affected by the depth of Lake Baikal in this place and distance from the coastline.

Flora and fauna

Baikal is unique in its flora and fauna: two thirds of animal representatives live exclusively here. Oxygenated water provides a favorable environment for the reproduction of species. Scientists have discovered only 70% of the fauna of Baikal. Epishura crustaceans form the basis of the lake's food chain, in addition, they perform an important function of water purification - they pass it through themselves. The fauna of Baikal has 56 species of fish. Among them is a unique species - golomyanka. The fish is interesting in that it does not lay eggs, but gives birth to fry alive. The golomyanka is 43% fat; in search of food, it migrates from great depths to shallow ones.

Nerpa is the only mammal that lives on Lake Baikal.

From flora sponges can be noted, which grow at great depths and are the oldest inhabitants of Baikal.

The uniqueness of the lake is recognized all over the world. Not only the depth of Baikal is taken into account, but also its unique ecosystem. Climate, geographical features lakes attract tourists and scientists from all over the world.

The etymology of the name of the lake has several versions. According to one of them, the word is Turkic and means "rich lake" - Bai-Kul. According to another, the name of the reservoir was given by the Mongols, and it means either “rich fire” (Baigal), or “big sea” (Baigal Dalai). And the Chinese called it "North Sea" (Bei-Hai).

The Baikal basin as an orographic unit is a complex formation of the earth's crust. It began to form 25-30 million years ago, and recent studies show that the formation process of the lake continues. According to geologists, Baikal is the embryo of the future ocean. Its shores "scatter", and after some time (several million years) there will be new ocean. But this is a matter of the distant future. Why is Baikal interesting for us today?

First of all, their geographical characteristics. The maximum depth of Baikal is 1637 meters. This is the highest figure among all the lakes in the world. The African, which is in second place, is lagging behind by as much as one hundred and sixty-seven meters.

The average depth of Baikal is also very great - seven hundred and thirty meters! The area of ​​the lake (more than 31 thousand square kilometers) is approximately equal to the area of ​​a small European country(Belgium or Denmark).

The depth of Baikal is also due to the huge number of large and small streams and streams (336!), Flowing into the lake. Only Angara flows out of it.

Baikal is also the world's largest reservoir of the purest in volume, slightly larger than all five great American Hurons, Erie, Michigan and Ontario)! In numbers, this will be more than 23,600 cubic kilometers. Great depth Lake Baikal and the impressive area of ​​​​the water mirror became the reason that the locals dubbed this lake lying in the depths of Eurasia the sea. Here, as on a real sea, storms and even tides occur, although they are of small magnitude.

Why is the water of Lake Baikal so transparent that at a depth of up to forty (!) meters the bottom is visible? The channels of the rivers feeding the lake are located in hardly soluble crystalline rocks, as is the bed of the lake itself. Therefore, the mineralization of Baikal is minimal and amounts to 120 milligrams per liter.

Given that the depth of Baikal is 1637 meters, and the coastline is 456 meters above the ocean level, it turns out that the bottom of the lake is the deepest continental depression in the world.

In August 2009 deep-sea vehicle"Mir-1" made a dive in the deep point Lake Baikal, not far from the dive lasted more than an hour. For five and a half hours, video filming was carried out at the bottom of the lake and samples of bottom rocks and water were taken. During the descent, several new organisms were discovered and a place was discovered where the lake is being polluted with oil.

For ten years, an autonomous deep-sea station has been operating nine kilometers from the coast at a depth of 1370 meters, which houses equipment for monitoring the Earth's electromagnetic field. Scientists expect that the depth of Lake Baikal will affect the accuracy of research, because the equipment is installed almost a kilometer below sea level. And a station for collecting, processing and transmitting information was installed on the shore to process incoming data.

Lake Baikal - what is it like?

In outline, Baikal looks like a narrow crescent, so easy to remember that it can be easily found on the map of Russia even by those who are not particularly strong in geography. Stretching from the southwest to the northeast for as much as 636 kilometers, Baikal seems to squeeze between mountain ranges, and its water surface is at an altitude of more than 450 meters above sea level, which gives every reason to consider it mountain lake. From the west, the Baikal and Primorsky ridges adjoin it, from the east and southeast - the massifs of Ulan-Burgasy, Khamar-Daban and Barguzinsky. And all this natural landscape so harmonious that one without the other is hard to imagine.

More Oleg Kirillovich Gusev (1930-2012), candidate of biological sciences, professional hunter, editor-in-chief of Russia's oldest magazine "Hunting and hunting economy" and author of several books on conservation issues unique nature of this lake, wrote: "Baikal gives us great joy and great pleasure." And he added: “It strikes with its monumental style and the beautiful, eternal and powerful that is inherent in its very nature”, emphasizing that the more you get close to it, the more tempting it becomes, and the more clearly you understand that Baikal is unique and charmingly inimitable. Anyone who visits here at least once can be convinced of the veracity of these words.

lake depth

The depth of the lake is truly impressive - 1637 meters. According to this indicator, Baikal surpasses such largest water bodies as Tanganyika (1470 m), the Caspian Sea (1025 m), San Martin (836 m), Nyasa (706 m), Issyk-Kul (702 m) and the Great Slave Lake (614 m). m). The remaining deepest lakes in the world, twenty-two in total, are less than 600 meters deep. A climatic conditions on Baikal, as they say, to match it unique features: here the sun scorches mercilessly and cold winds blow, then storms rage and the quietest weather sets in, conducive to beach holidays.

Features and mysteries of Baikal

The coastline of the Siberian "crescent" is 2100 km long, it has 27 islands, the largest of which is Olkhon. The lake is located in a kind of basin, which, as mentioned above, is surrounded on all sides by mountain ranges and hills. This gives reason to assume that the coastline of the reservoir is the same throughout. In fact, only the western coast of Baikal is rocky and steep. The relief of the eastern one is more gentle: in some places the mountain peaks are at a distance of 10 or more kilometers from the coast.

Lake Baikal water

23,615.39 km³ - such a fantastic figure measures the reserves of Baikal water. According to this indicator, the lake is second only to the Caspian Sea. Considering that in the latter it is salty, it is Baikal that occupies the first line of the world ranking in terms of fresh water reserves, that is, suitable for drinking water. In addition, it is extremely transparent, and all thanks to a very small amount of suspended and dissolved minerals, not to mention organic impurities - they are generally negligible here. At a depth of up to 35-40 meters, you can even distinguish individual stones, especially in spring, when the water turns blue. It also has a huge supply of oxygen. It is not for nothing that Baikal is called the national treasure of Russia for the combination of such unique properties and qualities.

The water in Baikal is very clean. Previously, it could be drunk directly from the lake and not even boiled. But now crowds of tourists have rushed to Lake Baikal, who still pollute this area, so now, before drinking Baikal water, you should ask the locals where this can be done.

Baikal ice

The time of freezing on the lake lasts on average from the beginning of January to the beginning of May. During this period, it freezes almost completely. The only exception is a small 15-20-kilometer section located at the source of the Angara. At the end of winter, the ice thickness can reach 1 meter, and even more in the bays - one and a half to two meters. At severe frosts Huge cracks form on the ice, which are called “stand cracks” here. They are so impressive that they can reach from 10 to 30 km in length. The width, however, is small: only 2-3 m. Such “slits” literally tear the ice cover into separate fields. If it were not for cracks, the formation of which is accompanied by a loud, like a cannon shot, sound, then lake fish would die en masse from a lack of oxygen.

Baikal ice has a number of other features that are unique to it, and truly mysterious, which scientists have not been able to explain. Back in the middle of the last century, specialists from the local limnological station discovered the so-called "hills" - hollow ice hills in the shape of a cone, reaching a height of 5-6 meters. Being "open" to the side opposite the shore, they even somewhat resemble tents. Sometimes there are "solitary hills", that is, located separately from each other. In some cases, they are grouped, forming "mountain ranges" in miniature.

Dark rings on the lake

Another mystery is the dark rings, the diameter of which is 5-7 km (moreover, the width of the lake itself is 80 km). They have nothing to do with the "belt of Saturn", although they were also discovered through satellite imagery. satellite photos amazing formations, made back in 2009 at different parts of Lake Baikal, bypassed the entire Internet. Scientists puzzled for a long time: what could it be? And they came to the conclusion that the rings arise due to the rise of deep waters and an increase in the temperature of the upper layer in the center of the ring structure. And as a result, a clockwise flow arises, reaching in some zones maximum speeds. As a result, vertical water exchange increases, provoking the destruction of the ice cover in an accelerated mode.

Bottom of Baikal

It is impossible not to say about the bottom of the amazing reservoir. It also differs from others, and above all in that it has a very pronounced relief - there are even underwater mountain ranges. The three main basins of the lake - northern, southern and middle, separated by the Akademichesky and Selenginsky ridges - are distinguished by a pronounced bed. The first ridge (his maximum height above the bottom is 1848 meters), is especially expressive: it stretches for as much as 100 km from Olkhon Island to the Ushkany Islands.

earthquakes

Another feature of these places is high seismic activity. Fluctuations of the earth's crust here occur regularly, but the strength of most earthquakes does not exceed one or two points. But there have been powerful ones in the past. For example, in 1862, when a ten-point “shake” led to the sinking of an entire piece of land in the northern part of the Selenga delta, one of the many tributaries of Baikal, under water. Its area was 200 km, about 1500 people lived in this territory. Later, a bay formed here, which is called the Failure. Strong earthquakes also occurred in 1903, 1950, 1957 and 1959. The epicenter of the latter, 9-point, was at the bottom of the lake in the area of ​​the rural settlement of Sukhaya. The aftershocks were then also felt in Irkutsk and Ulan-Ude - about 5-6 points. In our time, the region was shaking in 2008 and 2010: the strength of the tremors was 9 and 6.1 points, respectively.

Origin of Lake Baikal

Lake Baikal still hides the secret of its origin. Researchers often argue about its age, coming to the conclusion that it is at least 25-35 million years. The indicator is impressive, especially considering that the life cycle of most lakes, and in the first place glacial origin, does not exceed 10-15 thousand years. After this period, they either become swampy or filled with silty sediments. With Baikal, nothing like this has happened and is not happening. And, according to scientists, is unlikely to happen in the future. The lack of signs of aging is explained by the fact that the lake is ... a nascent ocean. The hypothesis did not arise out of the blue: as it turned out, its banks move away from each other by 2 cm every year.

Flora and fauna

An interesting fact: the purity of Baikal water is, by the way, very cold (temperature surface layers even in the warm season it does not exceed +8-9°C on average) - supported by the microscopic crustacean epishura, one of the most famous local endemics. In the course of its life, this 1.5 mm crustacean consumes organic matter (algae), passing water through its small organism. The role of epishura in the ecosystem of the lake can hardly be overestimated: it forms 90 or more percent of its biomass, serving in turn as food for the Baikal omul and predatory invertebrates. In the processes of self-purification of Lake Baikal, oligochaetes or oligochaetes also play a significant role, 84.5 percent of which are endemic.

Of 2600 species and subspecies local fauna More than half of aquatic animals are endemic, that is, living exclusively in this lake. Among the fish, one can also distinguish grayling, Baikal sturgeon, whitefish, taimen, pike, burbot and others. Of particular interest is the golomyanka, which, from a human point of view, “suffers” from obesity: its body contains about 30% fat. She loves to eat so much that in search of food every day she makes a “journey” from the depths to shallow water, which surprises researchers a lot. This underwater inhabitant is also unique in that it belongs to viviparous fish. The distant "neighbors" of golomyankas can be called freshwater sponges growing at great depths. Their presence here is an exclusive phenomenon: they are not found in any other lake.

If the biosphere of the lake is presented in the form of a pyramid, then it will be crowned by the Baikal seal or seal, which is the only mammal in this reservoir. Almost all the time he lives in the water. The only exception is autumn, when seals lie en masse on rocky shores, forming a kind of "settlement". Many other inhabitants of Baikal also explore the coast and islands, for example, gulls, goldeneyes, shelducks, mergansers, white-tailed eagles and other birds. Characteristic for these places is such a phenomenon as coming to the coast, and in droves, brown bears. And in the mountainous Baikal taiga you can meet musk deer - the smallest deer on Earth.

Attractions of Baikal

Lake Baikal is so majestic that it is often called the Siberian Sea. In 1996, it was listed by UNESCO as a World Heritage Site. world heritage. But not only due to the unique ecosystem that requires careful treatment - there are also many historical and architectural sights, not to mention natural and cultural monuments.

One of them is located near the lake, at the source of the Angara, a reserved rock called the Shaman-stone. It can be seen in the middle of the river, between capes Rogatka and Ustyansky. If you focus on the line ferry crossing"Port Baikal", then the rock will be 800 meters lower. Since ancient times, the Shaman-stone was endowed by the inhabitants of the Angara region with unusual power, they prayed near it and performed various shamanic rites.

Between the mainland and the Svyatoy Nos peninsula is perhaps the most famous bay on Baikal - Chivyrkuisky. Its area is approximately 300 km², it is the second largest on the lake, and it is also shallow (about 10 m deep). Thanks to the latter circumstance, the water in the bay warms up well, on average up to +24 degrees. On the southwestern coast there are such settlements as Kurbulik, Katun and Monakhovo. The main wealth of the bay is fish resources. Here you can find pike, perch, horned catfish, the weight of which can reach tens of kilograms. However, fishing on an industrial scale is prohibited - only amateur. The Chivyrkuisky Bay is also known for its thermal spring, one of the hottest: the temperature of the water used to treat diseases of the musculoskeletal system ranges from 38.5-45.5 ° C. The source is located in the Zmeina Bay, on the western side.

On northeast coast Lake Baikal is a tract belonging to the natural-geographical region Podlemorye. It is called Frolikha and includes the river of the same name, which flows into Baikal Bay Frolikha and flows out of the lake with the same name. In the river valley - its channel, by the way, crosses the famous a tourist route 95 km long - the Frolikhinsky nature reserve is located. Together with the Zabaikalsky National Park and the Barguzinsky Reserve, it is subordinate to the federal budget government agency"Reserved Podlemorie".

Rest on Baikal

It is along the Circum-Baikal railway In the 80s of the XX century, the Bureau of International Youth Tourism "Sputnik" (Irkutsk) developed the first ecological tour. Since that time, ecotourism on Baikal has been actively developing, despite the fact that tourism infrastructure here is not well developed, there are some transport difficulties. There are also problems associated with pollution. environment emissions from the Baikal Pulp and Paper Mill. But all of them are to some extent compensated by the activities for the creation and arrangement of excursion trails, regularly carried out by tourist organizations in the region.

The most favorable time for relaxing on the lake is from May to October. You can swim in July and August, since these months are the hottest - the air warms up to + 30 ° C, shallow water - up to + 25 ° C. Vacation on Lake Baikal will satisfy the needs of even the most demanding tourists. beach holiday, cycling and car tours, hiking along the coast, rafting on catamarans and kayaks, quad biking and even helicopter tours - these are far from complete list what travel agencies offer to their customers. Climbing coastal cliffs and descending into caves are popular.

Fishing

Fishing should be mentioned separately. Many amateurs fish from the rocks adjacent to the lake. The most reckless anglers prefer to settle in specialized bases, of which there are many, and which differ in different levels of comfort. They go fishing on rented vessels. The most popular places on Baikal for fishing the already mentioned Chivyrkuisky Bay, the Mukhor Bay, the shallow bays of the Small Sea and, of course, the rivers flowing into it are considered. The largest of them (besides the Selenga) are the Upper Angara, Snezhnaya, Barguzin, Kichera, Turka, Buguldeyka and Goloustnaya. And only one river flows out of the lake - the Angara.

Fishing, only now under the ice, finds its fans in the winter season, which here lasts from late December to mid-May. Fans of the "second Russian hunt" are helped by professional instructors: without them, it is difficult for inexperienced fishermen to do in an unusual transparent ice correct hole. They willingly share the secrets of how to organize comfortable rest in conditions of 40-degree frosts, which are not uncommon for Baikal. And those who do not want to test their health with extreme cold, go underwater fishing in March and April. At this time, the ice is still strong, and the air temperature begins to reach positive levels.

Winter sports

Of winter entertainment, tourists are also offered dog sledding (the routes are very different both in complexity and length), snowmobile rides ( excursion programs are also different and depend on the level of preparedness of the riders), riding skiing, sledges and snowboards (you can rent ski equipment at numerous rental points on the coast). In winter, as, indeed, in summer, helicopter excursions are held in high esteem among vacationers, giving unforgettable impressions for a lifetime.

Children and youth tourism

Sufficiently developed on Baikal and children's tourism involving rest in summer camps. We will immediately please parents: your children will not be bored here. Staying in a children's institution involves a rich excursion and creative program, including the holding of sanatorium and health-improving events at specialized bases. One of the most convenient places on Lake Baikal for families with small children is Mandarkhan Bay. It seems as if it was specially created by nature for this purpose: it is very shallow, and in summer there is perhaps the warmest water here and children do not risk catching a cold.

The youth is not left unattended. For her, the interregional public organization "Great Baikal Trail", established in 2003, implements various international programs, taking into account the specifics and needs of the age of up to 30. For example, the arrangement and reconstruction of ecological paths, holding educational lectures on nature conservation. Schoolchildren are also actively involved as listeners of the latter.

Hotels and recreation centers on Lake Baikal

Many tourists come to rest on Baikal, as they say, savages, getting on their cars. They choose a place they like on the coast and stop there, spending the night in tents. There are very few campsites specially equipped for motorists on the lake. If you plan to stop at such a site, you should take into account that there may not be firewood and basic amenities (for example, a toilet) in this place. Therefore, think in advance about how you will “survive”.

Such experiences will be spared by those who prefer to travel in comfort, even minimal. At their service are many hotels, recreation centers and guest houses scattered along the entire coast of Lake Baikal. Moreover, each tourist will be able to find the most suitable accommodation option for him - taking into account, of course, individual preferences and financial capabilities. We are forced to upset the bohemian public: there are no five-star hotels with the highest level of service here. She, like "mere mortals", will have to be content with ordinary rooms with all amenities. Another note: some recreation centers accept tourists only in the summer.

Tourists traveling on their own run the risk of running into unscrupulous intermediaries when booking a hotel room or recreation center. To prevent this from happening, book a hotel room only through proven and reliable services, which will not only save you from scammers, but also allow you to rent a room at the lowest cost, without unnecessary markups. We recommend Booking.com, one of the first and most popular online hotel booking systems.

How to get there

There are various ways to get to Baikal. The starting point is usually the nearby big cities: Irkutsk, Ulan-Ude, Severobaikalsk. Tourists first come to one of these settlements and already there they are planning in detail their further route. The trip on the section of the Trans-Siberian Railway between Ulan-Ude and Irkutsk is especially memorable: the lake stretches right outside the train windows and you can admire its magical panorama for hours.

One of the most popular places tourism on the Siberian Sea is the village of Listvyanka, located at the source of the Angara, it is 65 km from Irkutsk. From regional center You can get here by bus or boat, the journey time is just over an hour. All routes originate in Irkutsk water transport, plying not only on Baikal, but also on the Angara.

In southeastern Siberia, on the border between Buryatia and Irkutsk region is the deepest freshwater lake in the world - Baikal.

Geography and hydrography

Has the shape of a crescent. Its length is about 630 km, width varies from 24 to 80 km. The surface area of ​​the lake is just over 31.7 thousand square kilometers, which is comparable to the area of ​​countries such as Denmark, Belgium or the Netherlands.
The lake is located in a giant bowl-hollow, surrounded in the west by rocky ridges, in the east by gently sloping hills. The maximum depth of the lake is 1642 m, the average is 745 m.
Baikal is the largest reservoir in the world in terms of fresh water reserves - 23.6 thousand km3. Also, this lake is the oldest on Earth. Its age, according to scientists, ranges from 25-30 million years. The most amazing thing is that the shores of the lake gradually diverge, expanding at a rate of 2 cm per year.
The lake is fed by about 350 rivers and streams (data have not been specified since the end of the 19th century), the largest of which are Upper Angara, Selenga, Barguzin, Sarma, Snezhnaya and Turka. Only 1 river flows out of Baikal - the Angara.
The lake is located in a seismically active zone.

Water, flora and fauna

Baikal water, despite the complex ecological situation region, remains by far the cleanest in the world. It has very few dissolved minerals, organics and a lot of oxygen. In its composition, it is almost distilled. This is the only reservoir on the planet from which today you can drink water without purification and boiling.
The water is so transparent that in spring, when the vegetation of the lake has not yet awakened, the bottom is clearly visible, as if through glass, at a depth of 40 m.
The lake owes its purity to a microscopic crustacean - the Baikal epishura. The maximum size of 1 crustacean is no more than 1.5 mm; they are endemic, living exclusively in the waters of Lake Baikal. They are the most important component of the lake ecosystem. Up to 10 times a year, they pass the entire giant mass of lake water through themselves, filtering and purifying it.
The water temperature in the lake ranges from 0 to +20 degrees.
More than 2,600 species of plants and animals live in the lake itself, almost all of them are endemic, i.e. are not found anywhere else in the world - seal, omul, golomyanka, Baikal sturgeon, whitefish, grayling, yellowfly and others.
The coastal zone is also extremely rich in various representatives of flora and fauna - Siberian cedar, stilted trees, relic spruces, Barguzin sable, Olkhon vole, musk deer, Asiatic godwit and many other unique inhabitants.
