Bear Lake Monster

The Bear Lake Monster is a 19th-century regional legend of a giant, serpent-like creature, often called “Sharlie,” that inhabits the turquoise waters of Bear Lake on the Utah–Idaho border.

Originating from Shoshone lore and later popularized by newspaper reports in 1868, it is described as 30–50 feet long, sometimes with legs or humps, and capable of moving faster than a boat.

This folklore is often confused with the, now extinct, Bear Lake Giant Beaver that lived in North America roughly 10,000 years ago which could reach the size of small black bear and lived of aquatic plants versus trees like smaller beavers today.
