Not all monsters hide in forests or mountains. Some glide silently just beneath the surface, right in plain sight. And in the case of Northumberland County’s stretch of the Susquehanna River, something might be doing just that.
Local outdoorsman and licensed fishing guide Ken Maurer spent decades on the river without incident—until one night, the current carried more than just carp and catfish. It carried a mystery.
Maurer wasn’t the first to mention it. Nearly a decade ago, in the early 2000s, a close friend described seeing something strange—something big—moving in the water. He said it looked like a “small submarine about to surface.” Naturally, Maurer chalked it up to fish tales and exaggeration until he saw it with his own eyes.
It was during an evening fishing trip that the river revealed its secret. At first, Maurer thought it was a deer swimming across the current. But the shape changed direction—cutting upstream—and there was no head, no ears, nothing breaking the surface. Just a long, smooth disturbance in the water pushing a wake so large, it sent waves crashing against the shoreline.
“When it got closer,” he recalled, “there was nothing sticking out of the water. It pushed a wake that made waves that lapped up on the shoreline. At about 50 yards, it sank out of sight. Creepy.”
That wasn’t the last time he saw it. Over the next two years, the creature returned—always keeping its distance, always vanishing before it could be clearly seen.
Maurer wasn’t alone. Another fisherman, miles downstream, came forward after reading Maurer’s account in The Daily Item. He had seen the same thing—something large, dark, and fast, sliding silently through the river. The two compared notes and debated its identity. A seal? An otter? A massive beaver? But none of those made sense. The head never broke the surface. The behavior wasn’t right. In the end, the best guess they could offer was a fish—a huge one. Maybe a carp the size of a kayak.
But even that theory had cracks. Carp don’t swim like that. They don’t pull half the river with them in their wake. And they certainly don’t look like submerged submarines.
No one’s quite sure what it was. Sightings have dwindled in recent years, but the stories persist. One man. One creature. Multiple encounters. And no explanation.
Is it possible the Susquehanna has its own monster? It wouldn’t be the first. In Clinton County, folks whisper about the elusive Susquehanna Seal. Downriver near Wrightsville, eyewitnesses once reported a sea lion-like beast surfacing close to where the Veterans Memorial Bridge stands today. And in scattered river lore dating back generations, Susquehanna mermaids were said to comb their hair along the banks under the moonlight. Perhaps the Mystery Thing is simply the latest in a long tradition of strange aquatic visitors to these storied waters.
As Maurer wrote, “We live in a very civilized area. How could any creature live around here, on land or water, that we don’t know about?” It’s a fair question. But the river has always held its secrets well.
One thing’s certain: if you’re ever fishing near the confluence in Northumberland County, keep your eyes on the water. You might just catch a glimpse of the Susquehanna’s Mystery Thing before it disappears into the deep.
