Have you ever dreamed of a warm spring-like place during winter? In the eastern mountainous region of Liaoning Province, there exists a magical area known as the 'Geothermal Anomaly Zone.' Here, the underground temperature can drop to freezing in summer, while in winter, it is steaming hot, seemingly defying the natural laws of seasonal change. This peculiar phenomenon has attracted the attention of many scientists.
The 'Geothermal Anomaly Zone' is located in Huanren County, Liaoning Province, stretching from the Chuan Ying Gou, 1.5 kilometers south of the Manchu Town Government on the left bank of the Hunjiang River, to the foothills of Niutishan in Kuandian County on the right bank. It spans approximately 15 kilometers and covers an area of 106,000 square meters. In summer, while the surface temperature can reach 30°C, the temperature just one meter underground can plummet to -12°C, resembling a layer of ice. However, in winter, this area is filled with steam, and crops continue to thrive. Vegetables like scallions and garlic grown in greenhouses remain vibrant even during the harshest winter.
A similar phenomenon, known as 'Bingbingbei,' is located in the northwest of Shiban Yan Township in Linzhou, Henan, at an altitude of 1,500 meters. Here, ice forms in spring, yet winter brings waves of heat and pleasantly warm spring water. These occurrences have sparked a keen interest in the mysteries of nature, leading scientists to propose various hypotheses to explain them. Some suggest the existence of two underground gas storage zones that release warm air when cold and cold air when hot; others speculate about vast gas structures and special insulation layers underground that cause these strange phenomena.
Despite these hypotheses providing multiple explanations, conclusive evidence is still lacking. The reasons behind the formation of the Geothermal Anomaly Zone remain to be further researched and explored by scientists.
