The Ice Cave Never Melted

In summer, when the outside temperature is 20 degrees Celsius, the Ningwu cave remains below 0 degrees Celsius, preventing the ice from melting.
The Ningwu Ice Cave never melted
Ningwu is the largest ice cave discovered in China, located in Luyashan Mountain, Shanxi Province. Inside the cave is an impressive scene, made up of thick layers of ice, white columns and stalactites stretching from the ceiling to the floor. This scene reminds many people of the ice cave of Princess Elsa, in the famous Disney cartoon Frozen. The cave is thought to have formed in the ice age, about 3 million years ago

Ningwu Ice Cave is located at an altitude of nearly 2,300 meters above sea level and about 100 meters deep, famous for its ability to never melt. Even in summer, when the outside reaches 20 degrees Celsius, the inside of the cave still does not exceed 0 degrees Celsius

Scientists at the China Institute of Geosciences said that the cave always keeps the air cold thanks to the ki-like structure in the bowling game. Like a trap, in winter, cold air flows inwards, thickens and settles down, hot air overflows and escapes by convection. Ice is inside the cave as well as a lining to help stabilize the temperature. When warm summer air flows in, it is immediately cooled, so it does not cause significant fluctuations. Photo: Zhou Junxiang / Image China.

In 2005, the cave was recognized as a national park and opened to welcome visitors in the summer, from May to October.
