The Monster of Lake Tianchi

The "Monster of Lake Tianchi" in the Changbai Mountains in Jilin province, northeast China, is back in the news after several recent sightings. The director of a local tourist office, Meng Fanying, said the monster, which seemed to be black in colour, was ten metres from the edge of the lake during the most recent sighting. "It jumped out of the water like a seal—about 200 people on Changbai's western peak saw it," he said. Although no one really got a clear look at the mysteriouscreature, Xue Junlin, a local photographer, claimed that its head looked like a horse.

In another recent sighting, a group of soldiers claim they saw an animal moving on the surface of the water. The soldiers, who were walking along the side of the lake, watched the creature swimming for about two minutes. "It was greenish-black and had a round head with 10-centimetre horns", one of the soldiers said.

A third report came from Li Xiaohe, who was visiting the lake with his family. He claims to have seen a round black creature moving quickly through the water. After three or four hundred metres it dived into the water. Ten minutes later the monster appeared again and repeated the action. Mr Li Xiaohe said that he and his family were able to see the monster clearly because the weather was fine and the lake was calm.

There have been reports of monsters in Lake Tianchi since the beginning of the last century, although no one has seen one close up. Some photos have been taken but they are not clear because it was too far away. Many people think the monster may be a distant cousin of the Loch Ness monster in Scotland. They also think that there might be similar creatures in other lakes around the world. Scientists, however, are sceptical. They say that the low-temperature lake is unlikely to be able to support such large living creatures.

Lake Tianchi is the highest volcanic lake in the world. It is 2,189 metres high and covers an area of about ten square kilometres. In places it is more than 370 metres deep.
