The body of water known as Lost Lake is an interesting geological oddity. Each year the entire lake disappears during the winter. However, the disappearance is not due to evaporation. The entire volume of Lost Lake quite literally disappears down a hole! The small lake is located in Santiam Pass, Oregon, in the United States. The entire lake is part of the Mount Hood National Forest. The Native Americans called the lake: Kwoneksamach.” European Americans first discovered it in the 1870s. When it is present, Lost Lake is a small, shallow, closed-basin lake approximately 18 mi (29 km) southwest of Mount Jefferson.
Lost Lake Mysterious Nature
The entire region of which Lost Lake is a part is part of an extensive lava bed formed approximately 3,000 years ago. The source of the drainage is a lava tube formed during the period of volcanic activity. The lava tube is approximately 6 ft (2m) wide. During the Spring and Summer, Lost Lake is kept filled by the combination of rainfall and the prodigious volume of runoff from snowmelt in the nearby mountains. During the winter the inflow ceases, and the water drains away. However, exactly where the water draining from Lost Lake goes remains a mystery at this time.
