In which country are the four death valleys in the world located?

1. At the junction of California and Nevada, Microsoft Corporation of the United States, there is a world-wide valley, about 300 kilometers long, about 6 kilometers at the narrowest point and 26 kilometers at the widest point. On both sides of the valley, the cliffs are steep and dangerous. 1949 In the spring, an expedition with golden dreams happily came here to explore, but did not come back, and the whole army was wiped out. Since then, many explorers have tried to uncover the mystery of the narrow valley of death, and the consequences are no different from those of gold exploration teams.

Later, scientists used aerial reconnaissance and were surprised to find that this hell on earth was actually a paradise for animals. According to aerial survey statistics, there are nearly 300 species of birds, about 2000 wild donkeys, more than 20 species of snakes and 0/7 species of lizards in this valley. They can fly, climb, run and lie down, but they are very comfortable! The mystery of why this valley kills people and keeps animals has not been solved.

There is a famous Death Valley at the intersection of Naples and Lake Villeneuve. According to scientists' investigation, more than 4,000 dead birds and animals, large and small animal remains were found in the valley, including dozens of birds, 19 reptiles and more than ten mammals. Their deaths were not killing each other, nor were they collective suicides, let alone man-made. What is the root cause? I don't even know. More interestingly, the valley only kills animals and does no harm to people.

Third, unlike the two Death Valley in the United States and Italy, the Little Death Valley in Crotaki, kamchatka peninsula, Russia is a disaster, no matter people or animals! This valley is very small, 2 kilometers long and 300 meters wide, only 100 meter narrow, but the terrain is rugged and very steep. There used to be a large number of bones of wild animals such as bears, wolves, badgers and foxes in the valley. Up to now, more than 30 people have been buried in the valley, most of whom are explorers, followed by zoologists.

There are several reasons for killing people and animals in this valley: First, it is believed that there are many open-pit mines such as sulfur, and hydrogen sulfide and carbon dioxide are murderers; Some people think that the valley is narrow and the valley bottom is deep, and the thermal toxic hydroxy acids and their derivatives produced here are the culprit. But this is not enough to explain why people and animals can live in peace in a village a stone's throw from Death Valley.

Among the four valleys of death, the cave in Java Valley in Indonesia is the most magical. There are six big caves in this valley, all of which are big traps. Needless to say, the lives of people who have strayed into the valley caves are hard to protect, and even those who keep their distance are hard to escape. When people or animals pass through the hole, they will be dragged into the valley by strong gravity. Even if it is 6 or 7 meters away from the hole, it will be sucked in by the "magic mouth" and swallowed in one gulp! According to reconnaissance, there are so many bones in the cave that it is difficult to tell which are human bones and which are animal bones.
