Murphysboro Mud Monster: The Big Muddy Cryptid of 1973
In the summer of 1973, the small town of Murphysboro, Illinois, along the Big Muddy River, became ground zero for one of America’s most credible cryptid flaps: the Murphysboro Mud Monster aka Big Muddy Monster.
On June 25 around midnight, a young couple parked near Riverside Park boat ramp heard a piercing scream “like an eagle shrieking into a microphone.” A 7–8 ft tall creature, covered in light-colored hair matted with mud and river slime, lumbered toward their car. They fled to the police station. Officers later found 10–12 inch footprints, heard the scream themselves, and discovered a black slime trail leading to the river.
The next evening in Westwood Hills, two teens (Cheryl Ray & Randy Creath) came face-to-face with it just 15 feet away on their porch. They described a stocky ~350 lb biped, long arms, roundish head, matted dirty-white hair like an English sheepdog, foul stench, and eyes that some said glowed red. It stared briefly then walked off into the woods. Police searches with tracking dogs found more prints, broken brush, and splashing — but no creature. The case file remains open to this day.
Witnesses consistently noted it walking more erect than a typical ape — more human-like in posture and build, stocky like a football player, with that distinctive muddy white/silver hair. I can’t help but wonder if it could have been a feral human… were it not for those huge 10–12 inch prints that clearly rule out any normal person in my estimation.
I recently saw photos of the impressive bronze statue Murphysboro erected to honor the legend. It strikes me as strikingly human in form compared to the more ape-like depictions we often see in Bigfoot art. The broad shoulders, upright stance, and overall proportions feel closer to eyewitness accounts of a bipedal “man-beast” than a hunched gorilla. Does that match what people pictured from the 1973 reports? Or has the statue evolved the visual legend? Curious what folks think.
Southern Illinois has a rich cryptid history — this one feels especially grounded with multiple independent witnesses, police involvement, and physical traces.
If you’re in the Murphysboro area, near the Big Muddy River, or have family roots in Southern Illinois — have you or anyone you know ever had a sighting, heard strange screams/knocks, or found odd tracks? Have there been any more recent sightings or unusual activity in the years since? Do you think the Big Muddy Monster is still around?
