There is a lake in the Oregon Mountains, which once a year completely disappears during the summer and then reappears suddenly with the cooling of the weather.
The lost lake water, as it is called, flows into a tunnel formed after cooling the lava to the surface of the earth and which has been reopened following a natural phenomenon (either erosion or a volcanic eruption). In the rainy season, during autumn, the tunnel fills up and the lake seems like any other, but when the heat comes in the summer and the temperature grow, the tunnel hole begins to swallow all the water until its complete disappearance. This cycle is repeated year after year for more than 3,000 years, according to the researchers.
