Introduction to Crater Tianchi: Crater Tianchi is located on the top of Tengshan Mountain in the east of Qingyun Mountain in Yongtai. It was formed due to the eruption of an ancient volcano. It is in the shape of a curved oval, with a circumference of about 400 meters, an area of about 12 acres, and an average water depth of 1.5 meters in high water. There are rippling blue waves in the pool, green grass beside the pool, and there are many volcanic eruptions such as volcanic bombs around it.
There is an area of 11,000 acres of grassland under Tianchi, with a slope of about 25 degrees. The meadows are lush and the view is wide. Local herdsmen often graze here, presenting a pastoral scenery with beautiful mountains and clear waters.
