Introduction of Mammoth Hot Springs in Yellowstone National Park, USA

One of the main factors of terrace formation is calcium carbonate. Millions of years ago, the sea water at the bottom of Mammos area left thick precipitated limestone here. When the high-temperature acidic solution flows through the rock stratum and reaches the surface of the hot spring, a large amount of precipitated limestone is dissolved. Once in contact with air, some carbon dioxide in the solution will volatilize from the solution. At the same time, solid minerals formed and eventually precipitated in the form of travertine, forming terraces. Looking from a distance, the accumulated golden jade is crystal clear, and the hot springs left behind form beautiful and colorful steps along the hillside. The same scenery reminds people of our colorful pool in Huanglong, China. The difference is that Huanglong is a cold spring and mammoth is a hot spring.

Yellowstone National Park The underground thermal energy of Yellowstone National Park is abnormal, and this "super volcano" has shown signs of eruption.

Since July 23, 2009, Yellowstone National Park has closed some areas in the park. The official explanation is that the underground heat energy in Huangshi National Park is abnormal, and people are worried that it will overflow and burn tourists. On August 7, the US Geological Survey reported that American scientists will install temporary earthquake detection networks, GPS receivers and high-sensitivity hydrothermal thermometers in the park. Three days later, the Denver Post reported that Liz, a geologist of the US Geological Survey, found a "big bag" more than 30 meters high and 600 meters long at the bottom of the lake bed in yellowstone lake. On August 24th, the earthquake station of the University of Utah measured underground at the southeast of the south gate of the park 15km, and an earthquake of magnitude 4.4 occurred. This earthquake is "unusual", and the focal point is only 0.834 km from the ground! Therefore, geologists in the United States and Britain have warned that the abnormal phenomenon of underground thermal energy in Huangshi National Park is likely to be a precursor to the impending awakening of the "super volcano" there!
