Crocodile spitting beads (East Xiaotianchi source waterfall) introduction: The north bank of Tianchi is a huge natural dam, which is formed by the superposition of ancient glacier terminal ridges and mountain landslides. It is 289 meters high. The entire dam looks like a crocodile. tail, so it is called "crocodile dam". There is an artificial sluice built at the east end of the dam, named "Crocodile Gate". The water in Tianchi flows down, forming a 10-meter-high waterfall, which is called "Crocodile Spitting Pearls". The water splashes into the "Black Dragon Canyon" and merges into a mountain stream. It flows north to form a pool not far away, which is the East Xiaotianchi. "Crocodile Spits Pearls", "Ice Pool Silver Curtain" and "Suspended Spring Falls" are collectively known as the "Three Waterfalls of Tianchi".
