No One Knew How The Hole Could Swallow An Entire Lake. Now The Weather Phenomenon Astounds An Entire World.

At Lost Lake in Willamette’s national park in Oregon, a strange nature phenomenon is acting out every year for as long as people can remember.

At this certain time of the year, the lake is swallowed by a big hole. Where the water goes? No one really knows, The Bulletin writes.

Here’s the hole that fascinates an entire world.

During rainy fall and winter, no one notice Lost Lake. But when it’s getting warmer it’s like someone pulls the plug out of the bathtub.

When the rain season is on its way to ebb away the lake lose its water source and the water disappears in a big hole. Cool, right?

The explanation is lava streams. They are formed during volcanic eruptions when the lava flows beneath the surface. When the lava travels underground it can build tunnels. And when the tunnels or the streams collapse it forms a hole. Take a look at the illustration below.

According to Jude McHugh, spokesperson for the national park, the water from Lost Lake transpire down in the earth through the lava-stream, which fills up the other water sources in other places in the forest. Water sources that work as drinking water for the societies surrounding Lost Lake.

Isn’t our nature amazing?
