Da Yehai

The most eye-catching landscape on the top of Taibai Mountain, the main peak of Qinling Mountains, is the "dayehai", which is called "Xianhu". The lake is 3590 meters above sea level. It is the highest mountain lake in mainland China. Dayehai was developed in the Quaternary glacial period 60000 or 70000 years ago and is a glacial lake.

brief introduction

Taibai, the main peak of Qinling Mountains, is one of the most eye-catching landscapes. The lake is 3590 meters above sea level, which is the highest mountain lake in China. Dayehai is a glacial lake developed in the Quaternary glacial period of 60000-70000 years ago.

The lake is as clear as a mirror. The lake is filled with fog and mist, and clouds disperse and fog hides. The folk call this fog "divine tent". There is a small bird of the white crested Robin by the lake. It is as big as a swallow. It has black back, red brown chest and white stripes on the top of its head. It sings "chirp" and flies quickly. It flies close to the water, or stands on the rocks by the lake. It's not afraid to see people and it's cute. People call this bird "Jingchi boy". Guard by the pool day and night. As soon as there are fallen leaves in the pool, it carries them away immediately, making the water free of grass and dust. What's more interesting is that when one bird can't move the debris, it is usually two birds carrying them out of the water.

The mystery of formation

It is generally believed that dayehai was a glacial lake during the Quaternary glacial period of 60000-70000 years ago. Since no one has ever explored the geological structure at the bottom of the lake, its formation is also a mystery. Hu Jingyu described how he felt about the bottom of the lake after he went ashore. He said: "the bottom of the lake is thick with mud. It feels soft and smooth like a sponge. Occasionally, he can touch some broken stones." According to his description, experts believe that this is in line with the characteristics of mountain glacier landform. Guo Liyu, a geology professor from Xi'an University of science and technology, inspected the rock samples collected by the divers at the bottom of the lake. He said: "the rock surface is very smooth, slightly curved, and there are some small sliding lines on the surface, which is obviously the result of glaciation.". Professor Guo initially confirmed that the dayehai lake should be a glacial iceberg lake formed about 10000 years ago.

The mystery of Biology

According to the Taibai Mountain Management Bureau, in 1982, a group of experts in our province made an investigation on the lake, but no fish or shrimps were found in the lake at that time. Now, people can see a large number of krill like creatures living in the sea. It is said that there is a kind of bird on the edge of Lake dayehai, which can carry away the small leaves and other sundries on the surface of the lake. It is known as "water purification boy". In fact, this kind of bird is called baiding brook Robin, which lives on the "shrimp" in the lake.

Diver Di Qing said that he didn't find any other creatures like fish and shrimp in the process of diving. When he dived into the bottom of the lake, he turned on his flashlight and could see some red dots flashing constantly, but he couldn't confirm whether they belonged to plankton or not. According to relevant experts, due to people's pollution of the lake water and the evolution of organisms, it's not surprising that there are some fish and shrimps in the lake, which may have mutated in the cold plateau.

How deep is it

Taibai Mountain, the main peak of Qinling Mountains, is 3771 meters above sea level. It is not only the watershed of the north-south water system in China, but also the highest mountain range in the east of inland China. In the north and south of baxiantai, one of the peaks of Taibai Mountain, there are six icebergs and ice eroded lakes, of which the most noticeable one is the lake on the north side

The mountain top Lake, which is known as "Daye Lake" by the world, has a water area of 6818 square meters and an altitude of 3590 meters. It is the highest mountain lake in mainland China. There are no trees around it, but there are a few alpine meadows. In summer, the meadows are full of flowers, which adds a lot of charm to the lake water surrounded by angular boulders. The lake water overflows all year round. The water is clear, blue and spotless. At sunrise and sunset, silver waves can be seen flashing, like thousands of stars falling in the distance. In rainy season, the lake is rippling, like flying in the air, driving the wind down, like thunder. What's more amazing is that there is a kind of bird by the lake, named baiding brook Robin, which preys on plankton or small leaves in the lake. It is passed down as "Jingchi bird" and "Jingshui boy".

For thousands of years, many people have explored the depth of the "big Ye sea", but they have failed. In the early 1950s, three climbers from the former Soviet Union wanted to know the depth of Mount Taibai when they climbed it. However, due to the changeable climate of Mount Taibai, their desire to decipher the "Daya sea" failed.

Because of the snow in Taibai mountain all year round, the sea water is chilly, turning up and overflowing all year round, clear, blue and spotless. For thousands of years, due to its inability to detect, it has been covered with a layer of mystery. This expedition, called "exploring the Daya sea", was held to uncover this veil. In the setting sun, the frozen sea is like a full moon falling from the sky, lying quietly in the arms of the mountain top. This seemingly beautiful frozen lake, in fact, has set a great obstacle for the upcoming diving exploration activities, and there is unknown danger hidden in the calm. Due to the fact that the sea is still frozen and the thickness of the ice is more than 30cm, the staff broke the ice twice in the afternoon of the first day and in the morning of the next day, making preparations for diving into the sea. Early in the morning of the 28th, people from all walks of life were busy: breaking ice, measuring water temperature, preparing equipment, selecting seats, opening maritime satellite telephone At about 10:30, two divers, Hu Jingyu and di Qing, put on rubber diving suits in the cold wind, swam from the Northeast bank along the ice breaking waterway to the center of the Daya sea, and dived into the water about one third of the diameter of the surface. The sound of cold wind and high altitude reaction such as headache make the on-site staff and media reporters sweat for them. Through the display screen of the underwater camera, we can see that the two divers are swimming deep in the water one by one, and aim at the camera lens to show their condition in the water. About 20 minutes later, two divers surfaced. After landing, they announced that from the diving point to the "seabed" 18 meters deep. This activity is the first diving expedition at the highest altitude in China. The divers also found some red swimming animals in the water. What are they? It remains to be further investigated. At the same time, they solemnly handed a stone brought back from the "seabed" to a geologist at the scene. "Judging from the stone quality and grain of this stone, the Daya sea was formed more than 10000 years ago, which is indeed a glacial iceberg lake of Quaternary period," the expert said, holding a stone This is the first ice breaking expedition to break through the limit of Alpine diving, which is no less difficult than diving in the Antarctic and Arctic. Due to severe hypoxia at high altitude and low water temperature, the diving depth is 18 meters, equivalent to 37 meters under normal conditions. The divers said that the depth of 18 meters detected today is just the vertical distance from the diving place to the "bottom of the sea". As for how deep the deepest part of the sea is, it is still a mystery!
