Selbyville Swamp Monster

Also known as The Great Cypress Swamp Monster, Swamp Monster of Selbyville

A hairy, screaming creature of Delaware’s Great Cypress Swamp – a decades-old legend that peaked in 1964, when a local man in a fur coat played the part.

The Great Cypress Swamp straddles the Delaware–Maryland line south of Selbyville in Sussex County. Once covering 50,000 acres or more, it is the largest freshwater wetland and forest block in Delaware – a dark country of bald cypress, black tupelo and Atlantic white cedar, tannin-stained water, old drainage ditches and the scars of great fires, one of which smoldered for months in 1930 and earned it the local name “Burnt Swamp.” It is exactly the kind of place where monster stories grow.

For generations, people living near the swamp told of screams in the night and of a large, hairy creature that chased travelers on the lonely roads through the woods. The stories, passed along by word of mouth since at least the early 1900s, grew with each retelling, and local parents found them useful: a later Selbyville police chief recalled his father warning that misbehaving children would be sent “back to the swamp.”

The legend reached its peak in 1964 – thanks to a hoax. Fred Stevens, a 21-year-old Selbyville resident, was encouraged by his friend Ralph Grapperhaus, who worked for a local newspaper, to bring the monster to life. Stevens made a costume from his Aunt Dorothy’s raccoon fur coat, hid beside a road through the swamp at night and leaped out at passing cars, while Grapperhaus wrote up the encounters to sell papers. Crowds came from as far as Dover and Salisbury, Maryland, and some young visitors even left chickens as offerings.

The joke ended when it became dangerous. Pickup trucks full of monster hunters began cruising the swamp roads, some drinking and some firing guns, and Stevens wisely retired the costume. He told the story publicly to WHYY in 2015, standing at the edge of the swamp more than 50 years later. The Selbyville Swamp Monster lives on as a favorite Delmarva ghost story, even though its most famous appearances came from a raccoon coat.

Notable sightings

1. Early 1900sScreams in the swamp Great Cypress Swamp, Sussex County, Delaware

   Residents near the swamp began telling of nighttime screams and of being chased by a hairy creature. The stories circulated orally and are not tied to specific dated reports.

2. 1964The monster in a raccoon coat Swamp roads near Selbyville, Delaware

   Fred Stevens, wearing a costume made from his aunt’s raccoon fur coat, jumped out at passing motorists while his friend Ralph Grapperhaus published the encounters in the local paper. The stunt drew crowds from across Delmarva until armed monster hunters made it too risky to continue.

3. October 30, 2015The monster confesses Selbyville, Delaware

   In an interview with WHYY, Stevens described how he and Grapperhaus staged the 1964 scare, and how parents had long used the swamp monster to keep children in line.

What could explain it?

• The best-documented sightings, in 1964, were a deliberate hoax by Fred Stevens and Ralph Grapperhaus to boost newspaper sales, confessed by Stevens in 2015.
• Night screams in the swamp are easily explained by foxes, owls such as the barred owl, bobcats or other wildlife.
• Older stories functioned as cautionary tales, used by parents to keep children away from a genuinely dangerous swamp.
• Isolated roads, darkness and expectation make passing deer or bears easy to mistake for a monster.

Legend, culture and tourism

The swamp monster is a fixture of Sussex County Halloween storytelling and Delmarva cryptid lore. The Great Cypress Swamp itself is now protected and restored by the nonprofit Delaware Wild Lands, which manages around 10,000 acres of it for bald cypress and Atlantic white cedar restoration; access is limited.
