To live in Washington is to be spoiled by nature. And whether you prefer to sink your toes into the ocean or relax on the sandy shores of a glittering lake at a state park, you’ll have plenty of options for doing that here. But did you know we happen to have one lake that is rumored to be bottomless? The depth of Lake Crescent, while beautiful, is also full of mystery.

Lake Crescent is located in the vast and stunning Olympic National Park, in the northern foothills of the Olympic Mountains.

The lake is about 18 miles west of Port Angeles. The lake is a popular destination in the summertime, and it's easy to see why. It has such clear, pristine waters, and there are several great hiking trails surrounding it.
But ask anyone how deep Lake Crescent is and you're bound to get a shrug or a blank stare.

Nobody really knows, and many people -- even park employees -- will tell you it's considered bottomless.
If you look online, you might see the Crescent Lake listed as having a depth of 624 feet.

But further research will show that the measurers of that depth from over 50 years ago were limited to 624 feet by their own sounding gear. More recent equipment has measured it at 650 feet, but it may be much deeper in parts.

Generations of Native Americans would not go near it because of one of its legends. According to said legend, the Klallam and Quileute tribes fought a bloody battle beneath Mount Storm King, and the mountain got angry and threw a chunk of rock into the valley over the battlefield. The rock killed the warriors and dammed the river, creating Crescent Lake.
And as if that legend wasn't disturbing enough, there's also the Lady of Crescent Lake to consider.

In 1936, a woman named Hallie worked in a tavern on the lake. After two failed marriages, she met and married a man named Montgomery J. Illingworth that same year. Unfortunately, he turned out to be the worst of them all. After months of abuse, Hallie disappeared, her husband claiming she'd left him for another man. But in 1940, Hallie's body surfaced in the lake, almost perfectly preserved by the properties of the water. Although it was obvious she had been strangled, it took awhile to convict her husband, who finally spent nine years behind bars.
Despite these disturbing tales, Lake Crescent is extraordinarily peaceful.
