A mound of tree trunk floating in the blue water of the lake is probably not a strange thing. However, what if the logs were floated for 120 years without once ever sink?
Crater Lake in Oregon is the deepest lake in the United States with waters so blue. However, when looking closer, a unique sights seen. There is a tree trunk to oscillate. The logs are stable enough to hold a person standing on it.

Interestingly, it turned out to be a wooden rod in an upright position in a long time. It's no longer a matter of months, but the tree trunk with the nickname "the old man in the lake" has been floating in an upright position for at least 120 years.
The basic laws of physics mentioned, the float things will always have the center of mass is greater than the center of buoyancy. This means that long logs would float in a horizontal position, while the short logs will float in a vertical position.

"The old man in the lake" has a length of 9 meters with a diameter of 61 centimeters. By that measure, it should logs floating horizontally. However, it's strange, the wooden log floats vertically.

No one can decipher the mystery of the wooden log. However, a theory is that there are stones that get stuck in the roots remaining from the trunk. The weakness of this theory, there currently is no stone-related and it is difficult to prove that the incident ever happened.
Another opinion says that submerged logs will become more dense and heavy from time to time, while the edges are not exposed to water will remain dry. Therefore, it floats vertically.
The tree trunk was first discovered in 1896 by a geologist and explorer named Joseph Diller. He noted, the wooden log on the move. In 1902, Diller published the first scientific study on this wooden log. He revealed, in the five years since its discovery, the log has been moved as far as 400 meters.
The second experiment was resumed on July 1 and September 30, 1938 found that the tree trunk back to travel farther, about 99.9 km in 3 months time. Strong winds and waves had brought it to move. Until now, no one knows where it originated mysterious wooden rod.
And the Crater Lake was formed about 7,700 years ago when Mount Mazama erupted. This lake has a depth of 592 meters, making it the deepest lake in the United States and the ninth deepest lake in the world. *** [EKA | FROM VARIOUS SOURCES | SCIENCEALERT]
