Introduction to the Ten Thousand Years Ice Cave: The Ten Thousand Years Ice Cave was formed during the Quaternary Ice Age of the Cenozoic Era and has a history of 3 million years. What’s unique about it is that based on the climatic conditions outside the cave, there is no icing environment at all. However, the icicles inside the cave do not melt all year round, and the ice gets thicker as you go deeper. It is the largest ice cave ever discovered in the country and the rarest large ice cave ever discovered outside the permafrost in the world. In 2005, the Ningwu Wannian Ice Cave was selected as a national geopark in the fourth batch of national geological park reviews and is now nearly 100 meters deep. It is divided into upper and lower floors. You can go sightseeing on each floor by drilling ice holes, going down ice stairs and crossing ice stacks. Each level can accommodate dozens of people, and the cave is surrounded by ice. Icicles, ice curtains, ice waterfalls, ice flowers, ice Buddhas, ice beds, ice clocks, ice men, ice Bodhisattvas, etc. formed by ice are all very strange and strange. The large and small scenery in the cave are either exquisite and crystal clear, some are dazzling, some are graceful, some are majestic, and they are all amazing. It can be called a world of ice. What makes people even more amazed is that less than 200 meters away from the ice cave, there is a ground fire that has never been extinguished for thousands of years. The locals call it the Thousand-Year Volcano. This ice and fire are originally in conflict with each other, but they wonderfully coexist on the same mountain. It can be said to be a wonder of the world and a unique sight in China.
