Champ, Lake Champlain, Vermont: Resembling a plesiosaur, this freshwater lake monster has had over 300 reported sightings, and it’s existence draws in tourism for the lake.
Tessie, Lake Tahoe, Nevada/California: Washoe and Paiute tribes have reported Tessie’s existence since the 19th century, and sightings of the serpentine being continue to this day.
Illie, Illiamna Lake, Alaska: Natives of the fishing village say Illie, or whatever monstrous species inhabits the lake, is about ten feet long with a box-shaped head. It often rams into boats.
Altie, Altamaha-ha River, Georgia: The Tama tribe discovered the creature when they lived in the area, and it is described as sturgeon-like, with a crocodile snout and dolphin-like movements.
Chessie, Chesapeake Bay: Chessie is a sea serpent,and swims using a sine curve movement. It has been sighted multiple times, the last relevant report in 1997.
Bear Lake Monster, Idaho/Utah: It resembles a mosasaur or large crocodile, and it is about 17 feet long. Since the 19th century when Mormons first settled the area, there have been reports of it waiting by the shores to attach victims.
Sharlie, Payette Lake, Idaho: Native Americans in the area have long shared stories of an evil spirit that dwells in the lake, and in 1920 it was sited by western settlers. It was sighted often in the 1940s and since, and is described as 35 feet long, with a dinosaur head, camel humps, and shell-like skin.
Oklahoma Octopus; Lake Thunderbird, Lake Oolagah, Lake Tenkiller; Oklahoma: It is believed that perhaps multiple Giant Octopus inhabit these lakes, and the creature has been sighted many times. It is responsible for many deaths, according to reports, and the lakes have an unusually high unexplained drowning rate.
Kipsy, Hudson River: Resembling a plesiosaur, Kipsy is a more recent cryptid discovery, which many speculate is actually Vermont’s Champ who has swam downstream. A large manatee was sighted in 2006, though the two creatures look nothing alike.
South Bay Bessie, Lake Erie, Pennsylvania: The sea serpent has had numerous sightings since 1793, and is about 30 feet long with fins and thick skin. It is one of the most well-documented cryptids with consistent sightings that match up with previous reports.
Beast of Beaver Run, Beaver Run Reservoir, Pennsylvania: In 2011, park officials reported sightings of a 5-foot alligator in the Beaver Run Reservoir. The Fish and Boat commission was contacted, but since the reservoir was closed off from residential areas, workers were told to leave it alone and let it die in the cold winter. Sightings of it were harmless, as most of the time it was sunning itself or floating. That year,winter temperatures were low, and it is unclear whether it survived. It has not been spotted since, however.
Leelanau, Leelanau Lake Monster, Michigan: This creature inhabits two adjoining lakes in Michigan, called Leelanau, and has a long stump neck and long tail. It resembles a rotting tree stump, and may actually be an undocumented species. It was first reported after the Leelanau dam was built in the late 1800s.
Silver Lake Serpent, Silver Lake, New York: It is described as dragon-like, with tail fins and red eyes. It was first spotted in 1855 by fishermen.
Located along the northwest coast of the Lower Peninsula of Michigan in Leelanau County and Benzie County, the Sleeping Bear Dunes National Lakeshore was established because of its outstanding natural features, including forests, beaches, dune formations, and ancient glacial phenomena.
