detailed research let them all go but make sure they all register in the log ok then i'm off to meet them and give instructions. the purpose of registration is to ensure that everyone makes it out of the cave safely today this group of scientists has some unusual work ahead of them perhaps they'll find a new grosso or come across a unique crystal. according to the scientist estimates the cave is ten to twelve thousand years old. it's the only cave in russia which is equipped with special pods for tourists. when passing by. the researches wish for a geographical discovery. you must be very careful when climbing there so that you don't fall down it's slippery there's a lot of ice down there how big is the grotto pretty large it will be exciting for you was if we did not come back in an hour send someone to find us. the research is

a getting ready to crew to reach the reserved area of the cave and that's off limits to ordinary tourists the entrance to the protected zone is basically a narrow hole so be very careful and cautious who will go first what you are closely. about fifty grottos have been found inside congo ice cave it's also famous for its seventy underground lakes. as a biologist. today he together with his assistant. checking out the caves flora and fauna their task is to set up some traps and they hope to catch a unique inhabitant of the water. temperature inside the cave varies from freezing to above zero. the further away from the entrance the warmer it gets from minus fifteen degrees celsius that's around five degrees fahrenheit to four degrees

celsius or around thirty nine degrees fahrenheit wow look at i found yes yes. this is a winter. he's a frequent cave inhabited. look. i won't be surprised if. for the first time the scientists have the chance to explore the depths of the lakes. this one is called the lake of deception because the water appears to be moving here. what happens is that the rain water through the ice mountain and drip into the lakes in different places. movement. phenomenon interference. now we have to put out the bait. holds the trap and. over here they love this kind of sausage they would never. be very careful when putting it out so that we do

not lose the trap that's it. it's one hundred twenty one meters long but because water dissolves it's gypsum arches the grottos appearance constantly changes regular measurements are needed here. we definitely need to measure the protruding parts of the plate the results will enable us to predict future growth of development so that we can then lay out the safest route for visitors. today geologists are measuring one of the most beautiful grottos the difference in temperature makes it peculiar at the bottom it's freezing on top it's above zero celsius because of this. in the grotto only mites reaching from the floor. husband and wife. first met while working at a mine together he specializes in landslides another hazardous activities she is

a mineral surveyor. as a geologist nicholai researches different rocks and looks into their formation and structure but his job also involves making laser measurements of caves. or notes down the results to measure the entire grotto they have to record two thousand different points with the help of special equipment if you got it yes well that's good. just so i mean the whoredom said we are now on top of the rock slide which formed when the roof collapsed over. these rocks will eventually be washed away by underground waters in the cave will cease to exist so this is very precious to us today so we will be. oh hello you know good you know lights where ok i'll be there soon to change the boards ok rangers are in charge of

safety inside the cave every day long before the tourists arrive they have to check to see if they've been a collapse on the tourist trail to be sure that everything is fine with the lighting and the general condition of the roof so now everything is fixed the cave is rigorously checked on a daily basis after all one hundred thousand tourists on average visit the cave every year that's twice the population of congo order. on the loose rock has been scraped off with the help of this beacon i can observe the process of how the slabs moved down which it would be connotes a crack when such movement occurs now i have to strengthen the gypsum block here. a screw threaded anchor fastens the loose rock to a solid one behind. it's believed to be the safest method for the congo or ice cave . because it ensures that the five tons of rock stays on the roof and

doesn't fall into the tourist trap stop the cave has been open to tourists from around one hundred years and it's not seen a single accident in all that time. when i came here as a student and saw all this space and the way ice is formed i was struck by the beauty this energy power that ten years have passed and the cave has become a part of my life because. difficult to get through here we are almost there. meanwhile geophysicist your easter bunny found costs topography. have reached the polar grocer. not only the most bizarre ice crystals but also a wife that's lasted for centuries it melts neither in winter nor in summer here one can appreciate the beauty of ice crystallization. scientists first began using geo radar to take measurements of the ice inside the cave and it turned out to be

very effective. we have to crawl here. and then slide down to measure all the your regular unease of the ice formations. nicholai thought that if such a technique was being used to study ice in antarctica then why couldn't it be applied in a cave before that an ordinary fishing ice ax was used to measure the ice who takes a little time to measure a fairly large area with the help of this device scientists learned that in some places the ice is six meters thick. the state of the ice inside it depends on the range of temperatures created by natural ventilation when it's colder on the surface lower temperatures accumulate inside the cave forms there and freezes over k. the process is controlled by the external environment in other words the cave acts

as a kind of natural air conditioner. if we do these measurements every year we can understand how freezing and melting happens we would be ok and can even make conclusions about climate change. dispel your divers have never swum in the protected area of the cave before for the first time a team of underwater researches from the russian geographical society will dive into a barely explored part of congo's treasure trove. spill your divers are exploring the so-called arctic ocean a lake in a protected area of the cave. they found out that this underground lake is congo is biggest it's sixty meters long making it twice as big as the last one which we found on the tourist trail choice for the shit out of a person who has undergone an underwater spill yogic course can work literally anywhere after this includes as rescuers on sunken ships. this is the best

spillage of training. this group has already studied more than a dozen underground lakes and not just in russia they research caves all around the world cave diving is one of the most dangerous of occupations divers are often unaware of what awaits them underwater but that thrill of discovery is also a stronger force. that there's there's a passage passage over there it's about fifteen meters long hundred fifty centimeters tall it's very narrow stones are falling down thank god we found everything we wanted well down guys. off the cave diver has just made his tenth day a graphical discovery it took him three years to prepare for a dive into this lake they had to develop the necessary skills in the undead.

because even the sea. writers mistake could cost them their. peeves. if so.

funny absurd. if so. he survived war atrocities. to make a final decision. has changed his life and the world around him. by giving us. hope. and love to so many children.

nikolai the american worker on tape. half. the time. i am i i i i i i i i i. i. i i thank.

just like you know old times trade is during the traditional russian holiday of schroders to which bid farewell to windsor and take some souvenirs so out fast. this is because the city of congo is full of talented artists ceramicist and stone covers since the seventeenth century when congo was found it has been a major trading. back in the sixteenth century the conqueror of siberia yarmuk marched here with his own they ended up losing their way so the cossacks chieftain decided to set up here before heading to siberia he established a settlement at the ice mountain houses were built for his men so they could survive the winter and during that time they discovered

a cane under the nose of the next troops used it as a natural refrigerator. the newly found cave attracted many tempting them with its mysterious tales peter the great himself ordered a map of the cave to be drawn the task was fulfilled in the eighteenth century it was the world's first map of underground gotos in the late nineteenth century congo natives alexander litvinenko was the first person to conduct guided to is using them and despite its beauty the cave had many dangers but then didn't scan the german princess victoria and battenburg and her daughter louise some time later louise married a prince and became the queen of sweden it said that this is what she wished for on the singing stone. the map of the cave is constantly being updated nine hundred sixty four saw the first cave planned with photographs but science has

made great leaps forward since then nikolai punch a cough is developing a three d. model of the underground labyrinth he enters survey data from the tower grosso into a special program the three d. model makes it possible to clarify the relative positions of the caves and to establish their maximum size analysis of the measurements helps determine whether a collapse is likely to happen and that's important not only for the cave but also for the city. we should study the course if occasion occurring in congo or cave it has created such an amazing natural phenomenon that it has become a tourist attraction the course of a cation happening in congo means a lot of money is needed to relocate people to safe places and to build houses on stable earth. according to scientific research two thirds of the city's depressions due to cost of acacia the cracks on this building have been growing for several years now the apartment block is supported by

a special construction of iron girders they prevent the walls and ceilings from collapsing new cracks are a sign of cost of occasion taking place underneath. her home in please. there is a large crack here where water lee in it causes rocks and destruction but with a wall in the kitchen is wobbling. mice and hamsters attack us from under the floor they knock the floor and run all over here inside the rooms the walls have been ruined by the damp wall paper simply peels off and there's also a big hole behind this crib. but this was the reason the water pipes here. when temperatures drop so it simply freezes through and through here we have static minds speak. there is another crack on this side as well then we first punched in up and then put up and he can hear look this meek and has already

cracked the most was it that he has. when this apartment block was constructed a cast lake was filling up below the land under the building began to subside as if it was sinking into a bottomless chasm tenants were evacuated and scientists were brought in to study the situation. this house is located in the city center problem was that cracks appeared because a cavity formed under the house here to resolve the issue scientists were assigned to deal with it they researched it for two years their results became the basis for the new general plan of the city now every building is constructed based on the scientists recommendations which will. surprisingly all seven of the cathedrals in the city stand firm despite the fact that they were built long before people knew about cost. in fact the city's merchant history has been largely

preserved thanks to cost of occasion is prohibited from building high rise buildings in the old city in case cast caverns cause another collapse. is that very cabin which is so convenient for scientists to study. to get from one grotto to another one has to cruel sometimes upside down meter by meter grosso after growth or an experienced spell just leads the group. you have to crawl sideways thrusting awakes against the wall there will be a lake under your feet three meters please be very careful so that you do not fall down or drop any equipment. feels at home in the protected area even when the lights are off she sees every little change immediately protected area was found by accident in one thousand nine hundred

thirty five there was an expedition during which a worker found a hole which revealed tunnels and grottoes stretching for three and a half kilometers along with many lakes these are so-called organ pipes vertical channels that connect caverns with the surface their height can be up to twenty two meters as tall as a seven story building there are thirteen grocers in this. huge pieces of loose gypsum hanging from the ceiling weighing at least five turns the first explorers were so amazed by the beauty of the new cave that they chose to preserve it just as it was. the gypsum crystals are rare in our cave this is one of the places where there are large enough of the most well known cave of this type is in mexico where they grow fourteen meters high. power in our caves they are five centimeters but they're very beautiful. meanwhile punk off

continues his research first centuries people have been interested not only in the caves but also in the things that live there. in the old days people believed that there was a mammoth like animal living in the cave feeding on the earth and that the underground kennedys appeared because of it but in reality the cave is home only to a very small and harmless inhabitants because the huge sea of perm used to be here . is just a matchstick in size. material that falls into the lake during floods it has no one and is never found up on the surface it was named after the caves first. lucky find for nikolai and olga. wow great. happy can't believe it yes of course they often die in traps because water gets

boiled their wonderful. now we have to register it. that this is a very interesting species if this is the only organism in the perm region which is adjusted to living in a cave. there is a theory that we got into the depths of the cave at the beginning of the ice age the cold contributed to its quicker penetration under the earth. the best spell a photographer of the czech republic. has come specifically to take pictures of one of the largest cast caves of the year olds. in this old passageway an inscription made in one thousand nine hundred fourteen by princess victoria a battenberg and her daughter louise can be found. crystals that are many years old take the shape of roses and multifaceted mazes when temperatures drop. the more

plates grow or a funnel becomes deeper. large ice crystals cover the ceiling forming a bizarre fringe when it gets colder they transform into bundles of ice needles. and they're at their largest in march this is how i structures are hidden away from human eyes beneath. being to many places over the past twenty years i have been to very dangerous caves. but i would like to say that i am absolutely stunned by what i see here now both as a photographer and as an avid tourist it's fantastic. i know yes i am the queen of the coal i will lead you through it three kingdoms the kingdom of the cold my favorite the kingdom of stone and the kingdom of water i'm.

so totally amazed by the striking beauty in the mystery of congo the ice caves that even ready to forego the cold and darkness to prove their love one couple would hold hearts as even held their wedding in the case. of those who. are stone of love do you remember them as you wish when we came into the cave two years ago yes i do can you guess what's to marry me not to call her soon as it's right. what their medicare guests at least come in here to register your marriage in the colder five k. . of the cold grotto was soon named because the holes in the ceiling resemble a reef and above a guest was built here in nineteen eighty-four by a life having chosen one of the most beautiful grasses arena and alexander decided to get married here.

was. the magic of the giant underground lakes and grottoes and the frozen poetry of the ice bring people into a fantastic world of ancient caves. the practice of guided tours here is almost one hundred years old valentine wrapped continues the tradition of the first guy and. he loves the cave as if it were his own home. a dolphin swimming here in search of his beloved mermaid oh but he failed to find her and turned to stone because of the unrequited love. of the book before that everyone searching for love knocks on the dolphin and the dolphin sings and their wishes come true. in the past people used kerosene torches or candles in spotless to light up the cave but by the end of the

twentieth century electricity was installed. today a torchlight procession in the cave is only for special occasions and now it's in tribute to alexander clinic off thanks to him tourists can venture underground every day. clinic often guided tourist into the cave until his very death even to the point where he was almost blind he connected the past the present and the future it was a constant process an eternal link between the mysterious underground world and the buzz of life outside. the cave you.
