Stories of the Flathead Lake Monster, affectionately called "Flessie," have been around for hundreds of years. The legend originated in folklore from the Indigenous Kutenai people.

The legendary creature has over 109 reported sightings. Laney Hanzel, a former Montana Fish, Wildlife and Parks fish biologist described the common description to NBC Montana as "a creature 30 to 40 feet long. It undulates through the water and had steel black eyes."

One couple explained their experience in an episode of Destination America. One afternoon their boat battery died when they encountered a slow-moving, serpent-like creature.

Cromwell Island and the "Monster Mansion" in Lake Flathead is for sale for $72 million. With more than 348 acres of rugged land, the island hosts the massive villa, and guest house.

The main house was inspired by 16th-century French architecture, and its unfinished interiors allow the buyer to design and customize the style to their preference.
