On October 27, 2019 Lena Lang was on an inflatable pool toy on Lake Crescent in Olympic National Park during a windy day. Her friend witnessed Lena overturn in her inflatable. That was the last she was seen. Lena was wearing a black two-piece swimsuit and did not have any belongings with her. Lena did not know how to swim. Searchers, led by the National Park Service, spent two weeks searching by boat, air, dive teams, from shore, and using a Remove Operated Vehicle (ROV) with side-sonar capabilities. Lake Crescent has a surface area of approximately 5, 127 acres, with a maximum depth of over 600 feet.
