Lake Crescent is a magnificent body of water located entirely within Olympic National Park. It’s known for its brilliant blue water and its clarity, which is caused by a lack of nitrogen in the water inhibiting the growth of algae.

But as beautiful as it is, this lake is sadly the site of something quite sinister and unpleasant.

In 1936, a woman named Hallie Latham Illingworth married a local beer truck driver. Hallie was a waitress at Lake Crescent Tavern.

As the holidays approached in 1937, Hallie disappeared.

Jane / Flickr Hallie’s husband, Monty, told everyone that she had run off with another man. But no one heard from Hallie again, not even her family. Eventually, Monty moved to California with a woman from Port Angeles.

Three years later, in 1940, a woman’s body floated to the top of the lake.

What happened to Hallie’s body is called saponification, which gave her skin the consistency of Ivory soap.

Monty was arrested for Hallie’s murder and brought back from California for a trial.

John Westrock / Flickr Monty swore that Hallie was alive when he last saw her. But Hallie’s friends identified clothes worn by the dead woman as belonging to Hallie, and her old dentist testified that the woman’s dental plate was definitely Hallie’s. When rope used to tie Hattie’s body was found to match rope that Monty borrowed from a storekeeper on the lake, he was convicted and sent to prison.

Lake Crescent is a picturesque and peaceful place. But what happened here was definitely tragic.

If haunted houses exist, surely a haunted lake isn’t much of a stretch. After all, Washington even has a haunted hiking trail.
