Loch Ness

Loch Ness (Nice)

Loch Ness is located in the Grand Canyon in the northern Scottish Plateau of England. It is 39 kilometers long and 2.4 kilometers wide. It's small, but it's deep. The average depth is 200 meters and the deepest point is 293 meters. The lake is not frozen all year round, with steep banks and dense forests. At the end of Hubei, there is a river connected with the North Sea. Located at the northern end of the Grand Canyon fault across the Scottish Highlands, it is the largest freshwater lake in the British interior. It is 52 feet above sea level, 24 miles long and 1 mile wide, and the only channel to communicate with the outside world is the Nice River. The water temperature in Loch Ness is too low for swimming. The lake is full of peat, which makes the visibility only a few feet and the water depth is deep. In the 1960 s, it was 754 feet deep. 1969, an underwater exploration operation claimed that the water depth reached 820 feet, and the deepest depth measured by sonar was 975 feet.

In summer, the water temperature within 100 feet of the water surface can reach 12 degrees Celsius, but the water temperature below 100 feet remains at 5.5 degrees Celsius. So most fish and aquatic animals live near the water surface. Until 1980, people thought that there was no life at the bottom of the lake. However, in the Loch Ness project of 198 1, the Arctic Shire was found at a water depth of more than 700 feet. Is it possible that there are other unknown creatures living here?

The earliest record of water monsters can be traced back to 565 AD, when the Irish missionary St. Columbus and his servants were swimming in the lake. The monster suddenly attacked the servant. Thanks to the priest's timely rescue, the servant swam back to the shore and saved his life. In the next ten centuries, there were more than ten thousand pieces of news about the appearance of water monsters. But the children at that time didn't miss it, thinking it was just an ancient legend or nonsense.

It was not until April 1934 that London doctor Wilson passed by Loch Ness and happened to find the water monster swimming in the lake. Wilson quickly took a picture of the monster with his camera. Although the picture is not very clear, it clearly shows the characteristics of the monster: long neck and flat head, which looks like a giant reptile plesiosaur that died out more than 70 million years ago.

Plesiosaur is a huge aquatic reptile, which lived from/kloc-0 to 70 million years ago and was also a distant relative of dinosaurs. It has a slender neck, an oval body and a long tail. It has sharp teeth in its mouth and feeds on fish. It is the overlord of the Mesozoic ocean. If the Loch Ness monster is really a plesiosaur, it is undoubtedly an extremely precious prehistoric animal, and this discovery will also play an important role in zoology.

So after this photo was published, it quickly caused a worldwide sensation. With the "dinosaur fever" in the 20th century, people began to associate water monsters with plesiosaurs and paid great attention to them. 1960 On April 23rd, British aviation engineer Ding Side filmed more than 50 feet of film in Loch Ness. Although the film is rough, during the screening, a giant creature with a long black neck can obviously swim across Loch Ness. Some scientists who are negative about this changed their views after watching this film. The Royal Air Force and the Air Reconnaissance Intelligence Center analyzed Tinsted's film and concluded that "that thing is probably a creature."

In 1970s, scientists began to search for water monsters on a large scale with the help of advanced instruments and equipment. In August, 1972, Boston, USA, some photos were taken in Loch Ness with some underwater cameras and sonar. One of the photos showed a two-meter-long rhombic flipper attached to a huge organism. At the same time, sonar also found that there were huge objects moving in the lake.

1June, 975, the hospital sent an investigation team to Loch Ness and took more photos. Two of them are particularly interesting: one shows a huge body with a long neck, and it can also show two short flippers of the object. It is estimated from the photo that the creature is 6.5 meters long, and its forehead is 2.7 meters long, which really looks like plesiosaur. Another photo captured the monster's head. After computer magnification, you can see the short tentacles and wide mouth on the monster's head. The conclusion is that "there are indeed large unknown aquatic animals in Loch Ness."

The discovery of 1972 and 1975 was a sensation, which made people feel that it is urgent to solve the mystery of the water monster or capture the live plesiosaur. Since then, Britain and the United States have jointly organized a large-scale investigation team, sent 24 investigation boats in a long snake array, and dragged fishing nets across Loch Ness in an attempt to catch the monster at one fell swoop. But unfortunately, nothing was found except recording some sonar data.

Because chasing water monsters failed, negative views became popular again. A retired electronic engineer wrote in the British magazine New Scientist that the Loch Ness monster is not an animal, but an ancient pine tree. He said that there were many pine trees near Loch Ness more than 10,000 years ago. At the end of the ice age, the lake rose and many pine trees sank to the bottom. Because of the pressure of water, the resin in the trunk was discharged to the surface, but the gas generated from it could not be discharged. So these pine trees sometimes float to the surface, but release some gas on the surface and then sink to the bottom. To people in the distance, it looks like the head, neck and body of a monster. "

But this view cannot convince those who claim to have witnessed the monster with their own eyes. Moreover, in the late 1970s, some people took several photos of water monsters.

So, why can't people catch monsters so far?

This should start with the special geological structure of Loch Ness. It turns out that Loch Ness contains a lot of peat, which makes the lake very turbid, and the bottom can be less than three or four feet. Moreover, the topography of the lake bottom is complex, and there are labyrinthine deep valleys and gullies everywhere. Even giant aquatic animals can easily and quietly escape the detection of electronic instruments. There are many fish in the lake, so monsters don't have to go out for food, and the lake is connected with the sea, so it is easy for monsters to get in and out. Therefore, it is difficult to catch monsters.

But as long as the monster is not really found, the mystery is not solved. So far, no one can draw a conclusion about the existence of water monsters. In this regard, the British writer Chester said: "Many suspects have less criminal evidence than the Loch Ness monster, so they were hanged." This is a humorous and ingenious evaluation of the mystery of ancient and modern water monsters.
