When is the best time to play with the ancient mortar?

Best time to die: Ningde belongs to subtropical maritime monsoon climate, with warm and humid climate, with the annual average temperature of 14℃-20℃, the highest in July, the lowest in monthly average temperature of 28℃-29℃, 1 month, and the monthly average temperature of about 8℃. The landforms of Ningde are complex and diverse, including mountains, hills, basins, plains and other landforms, and the microclimates in different regions are quite different. Although there is a certain temperature difference between coastal and inland areas, in general, Ningde has a warm climate and abundant precipitation, and can travel all year round.

March-June is the rainy season in Ningde every year, with continuous rainy weather, and July-September is the season with frequent typhoons and heavy rains. When traveling to Ningde at this time, you need to pay attention to the weather forecast and prepare rain gear and other related items.

It is understood that the mortar is a direct product and an important relic of ancient glaciation and the climatic environment of ancient glaciers. It is a stone pit formed by glacier melt water carrying ice chips and debris, which strongly impacts and grinds the underlying bedrock from top to bottom along the glacier cracks. Because its shape is very similar to that of ancient stone mortar, it is named "ice mortar". The first discovery of mortars in China was in the 1970s, which was called the great discovery of China. Especially, there are a large number of ice mortars distributed on the ridges and peaks in the middle and low mountainous areas in eastern China, which can be called "the wonder of the world" and "the best in the world". No wonder many experts commented, "If the discovery of mortar can be finally confirmed, the history of Quaternary geological environment in the world will be rewritten!"

For this three-day arduous investigation, people in the tourism department of Fu 'an City said that it is enough to describe it with a sentence from Professor Han-"Life hangs by a thread". These ice mounds are mainly distributed in Baiyun Mountain Jiulong Cave Scenic Area and Jinzhongshan Long Ting Creek Canyon Scenic Area, and most of them are located in river valleys. Due to the steep mountains and numerous cliffs, it is in the original ecological state and its accessibility is poor. Under the guidance of local villagers, they moved a ladder six or seven meters long, followed the rugged path where the woodcutter entered the mountain to cut wood, and explored with experts, and embarked on a 6-kilometer-long investigation tour of glacier relics from Chanxi to Jiulong Cave.
