Why pangong tso lake is so blue in colour?

Pangong Tso Lake's striking blue color is primarily due to the high purity and clarity of its water, which contains very low levels of sediment and organic material. The lake's unique mineral composition, particularly high concentrations of magnesium and calcium, contributes to its vibrant hues. Additionally, the angle of sunlight and the lake's depth can influence the color, making it appear more vivid in certain conditions. This combination of factors creates the stunning blue shades that attract visitors.
