It shouldn’t be there. Seriously. If you toss a log into a body of water, it floats horizontally. That’s just basic physics—buoyancy and weight distribution doing their thing. But the Old Man of the Lake, a mountain hemlock log that’s been bobbing around Oregon’s Crater Lake for at least 120 years, doesn’t care about your physics textbook. It floats completely upright.
Standing about two feet out of the water, the bleached-white stump looks like a lonely buoy or perhaps the head of a giant swimming creature from a distance. It’s a bizarre sight. When you first spot it against the deep, "Crater Lake Blue" water, it feels like a glitch in the matrix.
He’s a local celebrity.
Geologist Joseph Diller first described the log in 1896. He noted that this strange piece of wood didn't just sit in one spot; it traveled. By 1902, when the area became a National Park, the Old Man was already a legend. If you think about the math, this log has been soaking in the deepest lake in the United States for over a century without rotting away or sinking. That alone is a miracle of preservation, likely thanks to the incredibly cold, pure water of the caldera.
The Physics of Why He Won't Sink
How does it stay vertical? Most scientists point to the root system. When the hemlock first tumbled into the lake—likely via a landslide—it probably had heavy rocks or dense soil tangled in its roots. This acted as a natural keel on a boat. Over the decades, the bottom stayed saturated and heavy while the top stayed dry and buoyant.
Even though the "keel" rocks are long gone, the wood at the bottom is now so much denser than the wood at the top that the center of gravity remains low. It’s a delicate, accidental balance. It’s also surprisingly sturdy. You can’t just push it over; it has enough buoyancy to support the weight of a full-grown human standing on top, though the National Park Service would strongly prefer you didn't try that.
The wood is white and splintered. It’s roughly 30 feet long in total, with about 28 feet of that hidden beneath the surface. Imagine a giant, wooden iceburg. That’s what you’re looking at.

Does the Old Man Control the Weather?
This is where things get weird. Native Klamath legends have long suggested that the lake is a place of great power, and the Old Man is often tied into the "spirits" of the water. But the modern ghost story comes from 1988.
During a submarine exploration of the lake’s floor, researchers decided the Old Man was a navigational hazard. He kept drifting into their workspace. To solve the problem, they tied him up near Wizard Island.
Then the sky fell.
Almost immediately after the log was tied down, a massive storm blew in. This was in August, a time when the weather is usually clear. The wind howled, and the lake became too dangerous for the submarine to operate. The story goes that as soon as the scientists untied the Old Man and let him roam free again, the clouds parted and the sun came out. Coincidence? Maybe. But nobody has tried to tie him up since.
A Floating Wanderer With No Destination
The Old Man is a traveler. He doesn't just sit in the center of the lake waiting for selfies. In 1938, a park naturalist named John Doerr tracked the log’s movements over three months. He found that the Old Man of the Lake traveled over 62 miles in that short window.
One day he’s near the Phantom Ship; the next, he’s crossed over to the north shore.

The log moves primarily because of wind and currents, but because it sits so deep in the water, it’s also affected by subsurface thermal movements. Because Crater Lake has no inlets or outlets, the water is remarkably still on the surface, but underneath, there’s a complex dance of temperatures. The Old Man is the only thing that lets us "see" those currents in real-time.
He’s honestly the world’s most low-tech tracking device.
Why He Hasn't Rotted Yet
Usually, wood in water lasts a few decades at most before fungi and bacteria tear it apart. Crater Lake is different. The water is so low in nutrients that "traditional" decay is incredibly slow. The water is also exceptionally cold. At the depths where the Old Man’s "feet" sit, the temperature stays a constant, bone-chilling 38 degrees Fahrenheit.
This creates a sort of natural refrigeration.
Furthermore, the hemlock species is naturally rot-resistant. Combine that with the lack of organisms in the lake that eat wood, and you have a recipe for a 120-year-old floating relic. Carbon dating on the log itself has suggested that the tree is at least 450 years old. It likely lived for centuries on the rim before it ever hit the water.
The Best Way to Spot Him
If you're heading to Crater Lake National Park specifically to see the Old Man, you need a bit of luck and a good pair of binoculars. Since he wanders, there is no "X marks the spot" on the map.

- Take the Boat Tour: This is your best bet. The rangers on the Volcano Boat Cruises are experts at spotting him. They usually know his general vicinity based on the morning's sightings.
- Watch the North Shore: He often gets caught in the currents around the northern side of the lake.
- Hike the Cleetwood Cove Trail: This is the only trail that takes you down to the water’s edge. If the wind is blowing the right way, he might be bobbing just a few hundred yards from the dock.
Be warned: from the rim, he looks like a tiny speck. Many people mistake random debris or shadows for the Old Man. Look for the verticality. Nothing else in the lake stands straight up like that.
What the Old Man Teaches Us
Beyond the folklore and the "weather control" myths, the Old Man of the Lake is a reminder of the lake’s extreme purity. Crater Lake is one of the clearest bodies of water on Earth. You can see down nearly 100 feet with the naked eye.
The fact that this log is visible from so far away, and has remained a constant figure for generations of visitors, makes it a symbol of the park’s resilience. In a world that changes so fast, there’s something comforting about a log that just wants to float upright and mind its own business.
He is a part of the ecosystem now. Moss grows on the part of the log that stays underwater, creating a tiny, floating habitat for microscopic life. He isn't just a dead tree; he's a moving island.
Actionable Tips for Your Visit
- Check with Rangers First: Stop at the Rim Village Visitor Center. They often have the "latest location" if someone reported a sighting that morning.
- Bring a Telephoto Lens: If you’re a photographer, a standard phone lens won't cut it from the rim. You’ll need at least a 200mm or 300mm lens to get a clear shot of the texture on the wood.
- Respect the Water: Remember that the Old Man is a protected feature of the park. If he drifts near your boat or the shore, do not touch or move him.
- Timing Matters: Early morning is usually when the water is flattest, making it much easier to distinguish his vertical profile from the waves.
The Old Man of the Lake doesn't have a schedule. He doesn't have a destination. He just is. And in the deep, silent blue of Oregon's high country, that's more than enough.
