●為什麼青池是藍色的？

青い池其實是個美麗的意外。話說1988年的十勝岳火山爆發，北海道開發局為了要保護美瑛，1994完成阻擋堰堤工程。

源自十勝岳的硫黄沢川中的鋁，和白髭瀑布(しらひげの滝)底下的美瑛川混和後，就產生了肉眼看不見的膠狀微粒子。

太陽光和水中的膠狀微粒子碰撞之後，便往不同的方向散佈。膠狀微粒子加劇太陽光線到處亂散，尤其是波長較短的青色光最容易亂散，到了我們的肉眼，就變成看的見的青色了。

這也就是為什麼不同角度和天氣下，遊客看到的青い池都不太一樣。

●Why is Blue Pond blue?

In 1994, Hokkaido Regional Development Bureau constructed a dam to protect Biei and to prevent mudflows that might occur from the volcanic eruption on Mt. Tokachi in 1988. Water blocked by the dam accumulates in the depression in the forest creating Blue Pond.

Aluminum in Iozawa-river deriving from Mt. Tokachi, generates colloid which is invisible to the naked eyes when mixed with the water of Biei-river.

the colloid, a solution of dispersed microscopic particles, reflects the shorter wavelength blue light.

That's why the color of Blue Pond changes depending on what angle the tourists look at it and even from different times of the year.

●神の子池水是哪裡來的？
●為什麼神の子池裡的倒木不會腐爛？

告示牌裡的大湖叫做摩周湖，摩周在愛奴語的意思是神，因為摩周湖最神奇之處，根本沒有河流進流出。這個神の子池是摩周湖的地下水湧出來的，那就是神的孩子囉～

神の子池每天湧出12000噸的水，池深5公尺，卻清澈似乎可觸底。由於摩周湖的水完全來自於融雪，所以神の子池水溫只有8℃，倒木不會腐爛。春夏秋因為日照強，會呈現鈷樣的藍，冬天就深藍色，還會有花羔紅點鮭穿梭倒木中(所以熊出沒注意)，花一小時慢活其中吧。

●Where is water of Kaminoko Pond from?
●Why do the fallen trees in the water never rot away?

The bigger lake in the billboard is Mashu lake. Mashu, which no rivers flow in and out of, means God in the indigenous Ainu language. Kaminoko pond is fed by underground well from Mashu lake; therefore, Kaminoko means the child of God.

Blue Pond has 12000 tons of subterranean water every day. Its bottom looks touchable but actually it's 5m deep. Water of Mashu lake springs from melted snow, so water of Blue Pond is at constant 8℃. That's why the fallen trees, looking like petrified wood in the pond, have never rotted away.

Due to the stronger sunlight, cobalt-blue sparkles in the pond from spring to fall, while it glitters dark blue in winter. Don't forget to watching Dolly Varden trout swimming amid the fallen trees (when it comes to trout, we should watch out for bears.)

投錢進神の子池，神明也不會保佑。
Gods don't bless you even if you throw coins into Child of God(Kaminoko) Pond.
