Lake Pukaki is also known as the Blue Milk Lake. It is also related to the glacier movement. After the fall of the Mount Cook Glacier, a basin was created under the erosion of the glaciers in the Southern Alps and the rocky side of the ice, and a large amount of snow and ice melted to form the barrier lake. In the mountains of the mountains, the lake is like a sea of blue water, poured into the rich milk, emitting a blue glow of milk under the sun. This is because there are a lot of rock particles and minerals in the lake, they are suspended in the lake water, reflecting the blue light of milk. When I came to Lake Pukaki, the trip was nearing the end. For this afternoon's arrangement, I simply wrote on the itinerary: Pukaki Lake is in a daze. This is the most beautiful lake I have ever seen in New Zealand, because the beauty of Lake Pukaki is too shocking, just like the biggest and brightest star in the sky, which makes other stars eclipse. This is the living environment I yearn for.
