message: Siberian Ice Caves
The ice accumulation and the coldness in the Siberian region have caused various types of cavities underground. Siberian ice caves have been able to form due to Siberia's high altitude and extremely cold climate conditions. The annual average temperature for the ice caves range from -4.0 to -0.6 celsius, annual average temperature for altitude is 44.7 celsius, and for more than 200 days the temperature is mostly in the negative. There have been more than 120 ice caves that have been discovered in Siberia. Most of the ice caves are discovered in Altai, Kuznetsky Alatau, Western and Eastern Sayan, Irkutsk amphitheater, and Zabaikal’e and Primori’e. Only some of them are found in the Prilenskoe Plateau and in the Valley of Aldan. Ice caves help with preserving Siberian long history. The speleological movement in Siberia was formed due to the discoveries of the many ice caves in the twentieth century. A lot of scientific research groups were formed to study ice caverns. Ice deposits have a huge amount of information about environment and climate conservation. The scientific data that was discovered from the ice caves were used to study the climate variations and precipitation fluctuations over the years. However, due to climate change the ice degradation became a problem in Siberia as it started to melt in the Northern Hemisphere. This makes it harder to preserve the untouched paleoenvironmental information stored. 1
Human DNA founded in the Siberian Cave
Scientists discovered a thumbnail size pendent that was found in the Denisova cave at the Altai mountains. The size of the pendant was roughly 0.79 inches, it was made out of a pierced deer tooth with a hole in it to wear it around the neck. The teeth have a porous surface which makes them trap DNA through skin or sweat or anything that comes in contact with it. Using modern tools scientists were able to separate the DNA without damaging the tooth and preserving it. It would require more research to discover where the DNA came from, but the researchers were able to find that the DNA belonged to a Siberian woman from 19,000 to 25,000 years ago. The teeth belonged to the deer species of elk also known as the wapiti. The DNA of the woman was discovered from the place where she lived after at least 25,000 years.2
Cave lion cub founded in Arctic Siberia
Cave lion cub was found frozen in the Siberian Arctic in the sleeping position. The cub’s golden fur was covered with mud and untouched. The cub’s organ, skin, teeth and soft tissue were all intact. Scientists say that the cub died 28,000 years ago but her claws are still very sharp to prick one’s finger. The cave lion was nicknamed as Sparta and was one of two lion cubs that used to roam around the northern hemisphere. They were found by hunters in 2017 and 2018 just 15 meters apart which made people think that those two lion cubs were related. However, according to the study, they had an age difference of 15,000 years. The cause of the death is not clear but there was damage to the skull, dislocation or ribs and skeletons were found. Scientists believe that this lion cub was the best preserved Ice again animal ever found due to its intact skin, organs and tissue.3
3500 years old bear discovered
The female bear was found by the reindeer hunter out of the permafrost on Bolshoy Lyakhovsky Island part of the new Siberian archipelago region in 2020. The exact location of where the bear was found was east of Bolshoy Etherican River. The extreme temperature helped in preserving the bear's soft tissue and its remains for 3,460 years. The bear is 1.55 meters tall and weighs around 78 kg. When the scientists cut through the bear, the pink tissue and yellow fat of the bear was clearly visible. They also sawed through the bear skull to get the brain out. According to the genetic analysis, this bear is not any different from the modern bear found in the northeast of Russia. The cause of death was the spinal cord injury and the bear was around 2-3 years old. However, it's not clear how the bear was able to get to the isolated island but its remains even after a long time was able to tell a lot about it. 4
Charioteer remains discovered
A 3000 year old grave of a person described as a charioteer because of the fixed metal attachment around the waist was found by archaeologists in Siberia. The fixed metal attachment was used for a belt so the charioteer can tie their reins to their waist. For a long time scientists were not sure of the use of the metal attachments. About 3000 years ago, Lugav culture had a tradition of burying people with bronze knives, bronze jewelry and unique belt parts. The discoveries of the human remains helped archaeologists understand better about Lugav culture.5
Ice Age wolf 
Furry head of the ice age wolf was discovered from the Siberian permafrost by the scientists. Scientists reported based on the tests that the wolf belongs to an ancient subspecies that lived at the same time period as the mammoths and then they both went extinct. The wolf size was 25% bigger than the modern wolf today and it was an adult wolf. Wolf had no fur or tissues but it still had its brain, ears and tongue intact.6
Climate change in Siberia
Siberian is known to contain permafrost that could also be used in a similar manner to ice caves for scientific discoveries. The research has revealed that speleothem growth showed the melting permafrost conditions. During the Marine Isotopic Stage, the climate got a little warmer than usual, causing a lot of permafrost to melt. Since Siberian permafrost stores a lot of carbon, melting would release a lot of carbon dioxide and methane to the environment. Scientists are using the permafrost activities in the past to predict what could potentially happen in the future as during the Marine Isotopic Stage a lot of permafrost melted and caused a negative impact on the environment.7
46,000 years old worm brought to life
A female microscopic roundworm that has been deep stuck in Siberian permafrost for 36,000 years has been discovered. When the scientist brought it back to life, the worm started to have babies through parthenogenesis Parthenogenesis which is asexual reproduction and doesn't require a mate. The worm can spend thousands of years in a cryptobiosis state that can last for infinity. In that state, all metabolic processes shutdown in the worm. After reading the worm's genome sequences scientists were not able to find its species.8
