Washington has more than its share of urban legends. After all, our state has more Bigfoot sightings than any other state. That being said, when it comes to creepy, sinister tales, it doesn’t get much eerier than the Lady of the Lake. Not only is it a true story, it’s one of the most enduring legends of the otherworldly Olympic Peninsula.

Lake Crescent is located in Clallam County, not far from Port Angeles.

The legend of the Lady of the Lake began in the 1930s, when Hallie Latham Illingworth moved to the area and married Montgomery “Monty” J. Illingworth.

The marriage between Hallie and Monty was extremely volatile.

In the summer of 1940, a woman’s body floated to the surface of Lake Crescent.

Of course, the public soon learned of this grisly discovery, and the woman became known as the Lady of the Lake.

Monty had moved to Long Beach by then, where he’d moved to be with a woman he was seeing before Hallie’s disappearance. He was arrested and found guilty of Hallie’s murder, serving nine years of his life sentence before he was paroled.

Lake Crescent is beautiful and peaceful. It’s hard to imagine that it once turned a woman into soap.
