The three princesses of revenge and the three princes of the snow shadow

[69 Book Bar-www.69shu.com] Information about Death Valley in the United States:

Origin of the name

No one knows the hottest place in North America: Death Valley Indians have left cultural relics here dating back 9000 years, but the notoriety of "Death Valley" wasn't earned until 150 years ago. In the winter of 1849, a gold panning team headed for Jinshan took a shortcut and crossed the valley. Due to the harsh weather here, piles of bones were added to the boundless yellow sand.The few people who successfully crossed the valley said "goodbye death valley" sadly when they left here, so the death valley got its name.

In addition, due to the arid and raging fire-like climate here, many gold prospectors who took Death Valley as a shortcut to California were unfortunately buried in the ruthless desert, and the reputation of Death Valley in the United States spread like wildfire.

Formation process

Death Valley was formed about 300 million years ago. The cause was that the earth's gravity crushed the earth's crust into huge rock blocks. At that time, some rock blocks protruded into mountains and some sloped into valleys.Until the Ice Age, the overwhelming lake water poured into the lower terrain and submerged the entire basin bottom. After millions of years of steaming and scorching by the flaming sun, this great salt lake left over from the ancient century finally dried up.Death Valley, which is exposed to nature today, is just an accumulation of layers of mud and rock salt.Edit this paragraph Geographical location In the mountains adjacent to California and Nevada.

"Death Valley" is 225 kilometers long and 6 to 26 kilometers wide, covering an area of ​​more than 1400 square kilometers.The two "banks" of the canyon are precipitous, and the terrain is very dangerous.Its lowest point is -86 meters above sea level, which is the lowest point in the United States.

Climate characteristics

Death Valley in the United States Death Valley in the United States is the hottest and driest area in North America.There is almost no rain all year round, and there are even records where the temperature has exceeded 100 degrees Celsius for several consecutive weeks.Whenever it rains cats and dogs, the hot place will rush into mudslides.There is also an "extinct crater".Because the temperature here is quite high in summer, often above [-] degrees, if the astronauts land in the space capsule without the cooperation and response of the ground personnel, the consequences will be quite dangerous.In the past, many people lost their way after entering Death Valley because of their adventures, and were unable to get out. As a result, they died of heat and starvation here.

During summer, due to the influence of the high temperature, a large number of rising warm air will form clouds above the valley, and when enough clouds gather, the rainfall will fall and cause short showers. In this way, the wild flowers and plants in the valley will be moistened by the rain. All over Death Valley.

Apart from rattlesnakes, the animals that live in this place include desert geckos, foxes, bighorn goats, eagles and yellow warblers, and most of them come and go before sunrise or in the evening.

In addition, 100 years ago, various minerals such as gold, silver and copper were discovered here, so there was a mining boom in Death Valley during that period, and the mining sites of that year are still preserved.In the 20s, borax was discovered again, and many people came to mine it.There are also rich minerals such as mica ore, limonite, hematite, and hill ore.Looking at the Death Valley in the United States from the air, it forms a colorful pattern, and it is a mineral deposit that has not been really mined in the United States.But generally go in, there is no way out.

There is an exploration team in the United States who is looking for gold mines, and they are willing to go to Death Valley because they get lost and get involved in it, and almost the whole team is destroyed.A few lucky escapers also died mysteriously soon after.Since then, some people who went to explore or try to unravel the mystery of Death Valley have also been buried in the valley repeatedly.Later, scientists used aerial reconnaissance to discover to their astonishment that this living hell on earth was actually the "Elysium" of birds and beasts.

According to aerial survey statistics, there are more than 300 kinds of birds, thousands of snakes, 500 lizards, and more than [-] wild donkeys in this Death Valley.They fly, crawl, run, or lie down, so uncomfortable.To this day, no one can figure out why this canyon is so cruel to humans, but so kind to animals.

Mysterious phenomenon

There is an unexplainable geological phenomenon in Death Valley, California, USA-the stones on the ground will move by themselves and leave parallel sliding marks on the ground!

These strange stones are indeed sliding on the ground. There is wind in Death Valley, but it is not enough to blow these stones.Although we have not actually witnessed the actual movement of the stone, it appears from observations that this substantial movement exists.Strong winds had been heard on the 27-mile course at Death Valley's Great Basket Crater before, but the winds at Runway Basin, despite their strength, were unable to move the stones.

Millennium Bacteria

The area where ancient bacteria were found According to the British "New Scientist" magazine, American scientists have discovered that bacteria that have survived for 3 years have been found in a salt crystal, and they feed on the remains of algae that are also imprisoned.This is the most convincing illustration yet of an organism's long-term survival.University of Hawaii microbiologist Brian Schubert and colleagues studied salt crystals in sedimentary cores extracted from California's "Death Valley."Salt crystals contain tiny pockets of fluid, and Schubert's team found that archaeal colonies can survive on samples of these fluids.They dated the liquid between 2 and 2 years ago.

Archaic colonies can grow with the help of liquid in salt crystals, and the history of salt crystals can be traced back to 3 years ago.This isn't the first time scientists have discovered that bacteria can grow through liquid pockets inside salt crystals.Prior to this, a research team reported that they had successfully grown bacteria using fluid from 4 million years ago.However, some have questioned the latest findings because salt crystals can break down and recrystallize over time, trapping modern bacteria.Schubert explained that the structure of the salt crystals they found suggested that they formed in hypersaline lakes.Robert Hazyn of the Carnegie Institution for Science in Washington, USA, said that Death Valley has no perennial lakes that are at least 2 years old, suggesting that recrystallization never occurred, supporting the idea that the salt crystals are what they appear to be. It's as old a claim. Hazzin has disputed several previous studies like this one.

This Death Valley is really scary.
