Description of the series:
The Emerald Lake
Emerald Lake is originally called “Dachaidan Lake”, located in Haixi Mongolian Tibetan Autonomous Prefecture in Qinghai Province， covering an area of 6 square kilometers.
The lake is in the mining area of the former Dachaidan Chemical Plant, which was abandoned for various reasons. The salt lake is formed after years of mining where halide (water) and minerals (crystals) collected after the exploitation of resources in the mining area. With the gradual popularity gained via tourism and photography enthusiasts, the beauty of Dachaidan Lake is suddenly revealed to the visitors. The color of the lake is as green as emeralds, so people gave it a beautiful name: “Emerald Lake”.
Emerald Lake is rich in minerals such as potassium, magnesium, lithium, and other metal elements and halides. It contains high concentration of salt water, which is called brine by the locals. Due to the high altitude and complex geological structure of the lake, the subtle chemical reaction between the lake water and underground minerals has become the beautiful lake as we see now.
Emerald Lake is composed of residual salt mud, textured pavement, scattered small lakes. The salt bed turns alternately light green, emerald green or dark blue according to the sunlight at different time. I photo the lake with a drone to capture beautiful jade like jewels bestowed by Mother Nature and to share with the viewers the picturesque landscape.
