Yellow Dragon(Huanglong in Chinese) National Park in southwestern China's Sichuan's Aba Tibetan and Qiang Autonomous Prefecture is a land of wonder.
The main attraction of the valley is the 3.6-kilometer-long and 30 to 70-meter-wide pale yellow calcareous deposits. At the end of the valley, water from melting snow mixes with limestone water from underground, flowing down the mountain terraces, depositing the calcium carbonate from the limestone water on the rocks, stones, and fallen branches in its path. The calcium carbonate, in turn, develops into solid, low travertine banks and reacts chemically with organic and inorganic substances, resulting in various kinds of calcareous deposits that reflect a golden color in the sunlight in the water that flows down the slopes just like a huge yellow dragon flying down the snow mountain. When water flows into two separate streams, it naturally turns into more colorful lakes and waterfalls, forming a ladder-shaped lake group. The water is crystal clear. The mineral deposits at the lake bottom look like jadeite and agate – magnificent and beautiful.
