The highest salt mountain has accumulated 300 million tons in a hundred years. Why do you have to bring a pack of salt to visit?

Compared with ordinary scenic spots, wonderful? Our scenic spots are more popular with tourists. For example, the highest salt mountain in the world is located in the German town of Heeringen. The whole mountain is made of salt, so it's called? Yanshan? . In the past, Yanshan Mountain was just an ordinary mountain, which was unknown to the world. Later, the local government built Yanshan into a famous scenic spot. At the same time, the relevant departments have formulated a regulation: every visitor to Yanshan must take away a pack of salt. Why are there such strange rules?

First, the Yanshan Mountains are about 530 meters above sea level, and there is too much salt to be treated. This salt mountain is located in Heeringen. In the past, Hillingen was low-lying, and water from high places flowed into Hillingen. The water in the lower part gradually evaporates, leaving a lot of potassium-containing salts. Local miners processed potassium salt into potash fertilizer and then transported it away, leaving a lot of salt. With the increase of mining, more and more salt is left, and the altitude of Yanshan Mountain is getting higher and higher.

Second, a large amount of potassium-containing salt will salinize the land. In ancient times, salt, as an important means of subsistence, was difficult to mine. However, due to the improvement of modern science and technology, it is no longer difficult to mine and process salt. Schilling's salt is no longer an indispensable living substance, but has become a dispensable substance. As we all know, only when the land is fertile can we grow high-quality food. Every rainy season, when the rain falls on the salt mountain, a large amount of potassium salt will melt in the rain and flow into the low-lying land. Excessive potassium will accelerate the salinization of land and make local farmers miserable.

Third, every tourist takes away a bag of salt, which can make Yanshan disappear quickly. In order to solve this problem, the local responsible person decided to develop Yanshan into a tourist attraction. On the one hand, the salinization of land makes farmers' harvest poor, and the development of tourism can drive the town economy and increase residents' income. On the other hand, every tourist brings a bag of salt, which can make the Yanshan Mountain disappear quickly.

However, it is not difficult for tourists to take away a bag of salt. Tourists can take this bag of salt as a souvenir.
