One lake in central Oregon disappears down a 6-foot wide hole, and no one really knows where it goes.

Lost Lake, located in the Cascade range in Oregon, is the result of a volcanic activity over a 1,000 years ago. Water levels on the lake change drastically throughout the year, but it drains completely through a hole during summer because the inflow of water is less than the drainage of the hole.

Over the years, there has been a problem with people trying to plug the hole with various debris, including car engines. Officials strongly discourage anyone from plugging the hole as it would lead to flooding and road damage.

The lake eventually becomes a meadow later in the summer.
