"Oregon Lake" Mysterious Why disappear every year?!!

In the middle of Oregon's forests, every winter, something strange and unusual happens. About 130 miles from Portland, in the south-eastern direction, lies a mysterious lake, which is said to have been formed about 3000 years ago. Every year in winter, this mysterious lake is lost. ! Yes, it disappears entirely through a hole in the ground, leaving behind a green that is filled again in the wake of the spring because of the snow melting from the surrounding mountains.
It is a phenomenon that fascinates scientists and simple curious. Every year, in the spring, Willamette National Forest Lake, Oregon, in the United States, disappears into a huge hole, reports the Huffington Post.
"It fills up during the winter, when the water supply through the melted snow is greater than the evacuation, then dries before becoming a meadow," says National Park spokesman Jude McHugh.

According to him, this phenomenon would be the result of the presence of a lava tunnel, a geographical feature of this region with a volcanic landscape.
Several people have tried illegally to fill the hole in the "Lost Lake" for years. Pieces of car, various gear and other debris in the pit have even been found, probably to obstruct it.

It is a mysterious phenomenon that occurs every year in the United States. During the dry season, a lake in an Oregon forest disappears completely. The water of this lost lake, as it is called, rushes into a hole formed by an old lava flow. But where does such goes next Nobody really knows .... According to the spokesperson of the national forest, the water is probably absorbed by the porous rocks, located below the surface. In winter, the lake reappears little by little. When rains exceed the water absorption rate. This natural phenomenon has been filmed, and the video has already been viewed by over a million Internet users.
