Dachaidan Emerald Lake is a magnesium sulfate subtype salt lake, originally a mining area of the salt lake mining team of a chemical plant, and is the third largest artificial lake in Haixi Prefecture. Due to the high salt content in the lake water, it does not freeze in all seasons. The lake is rich in various elements such as potassium, magnesium, lithium, etc., at different concentrations, hence it displays different colors. The Emerald Lake is clear and transparent, and through the water surface, one can clearly see the salt layer at the bottom of the lake. The inner layer of the Emerald Lake is blue-green, while the outer layer is milky blue, and through the water surface, one can clearly see the salt layer at the bottom of the lake.
