Lake Pukaki, like Lake Tekapo, is a glacial lake formed by meltwater from glaciers in the southern Alps. In my eyes, they are as amazing and beautiful. Compared with the unique emerald green color in the blue of Lake Tekapo, Lake Pukaki is particularly dazzling in color. It looks like milk-white milk poured into the blue water of Lake Tekapo, and the color of milk-blue shines in the sunshine. This is because the lake contains a large number of rock particles and minerals brought about by glacial melt water, which are suspended in the lake water, so that it reflects a unique and dazzling light. Therefore, Lake Pukaki is also known as "Blue Milk Lake". Lake Pukaki is also an excellent place to look at the majestic southern Alps. The Alps guard the gentle and quiet lake like a goddess with its magnificent shore, and project his figure into the clear water of the lake, making it more picturesque and beautiful.
