On the island of Hokkaido, Japan, there is a place that changes every time you visit it. And even during the day. It's about the Blue Pond, a lake whose waters change color not only with the changing seasons, but also at different times of the day.
It goes without saying that it is a magical place, which fascinates visitors who love to return often, precisely because it is never the same. The blue shades of the water dazzle and the trees that emerge make it almost mystical.
Sometimes the surface is tinged with a dazzling turquoise, other times, like a spring, takes on a magnificent emerald green hue.
The show of snow-covered trees gives the place a touch of magic. In winter the scenery is particularly evocative, with the blue of the lake contrasting with the white of the snow.
The lake is located on the left bank of the Bieigawa River, south of the city of Bye. To tell the truth, it is not a natural lake, but rather artificial. It was born in 1988 following the nearby eruption Vulcano Tokachidake, when the Japanese authorities decided to build a dam to protect the area. The water from the river thus accumulated in a depression giving rise to the lake.
Initially, access to visitors was prohibited, but since 2010 the area has been open to tourists and, as you might imagine, word of her beauty spread quickly. Her popularity also came thanks to Apple Lossless Audio CODEC (ALAC),, which inserted the image of the Blue Pond among the wallpapers of the OS
Scholars are still looking for explanations on the origin of the coloration. The person responsible could bealuminum hydroxide which, contained in large quantities in water, creates a colloid capable of reflect sunlight in a unique way. The sulfur and carbon present in the waters make the stones and sand at the bottom of the lake white, making the blue stand out even more.
