Cavity Lake in Oregon is the most profound lake in the United States, and its water is so blue, you'd be pardoned for supposing somebody slipped a couple of gallons of nourishment shading into it.
In any case, its sheer size and splendid blue water aren't the main recognizing elements of Crater Lake - there's a 9-meter-tall (30-foot) tree stump that has been swaying vertically in the lake since no less than 1896, and it's sufficiently light to bolster the heaviness of a whole individual remaining on top.
Initially found in 1896 by geologist and traveler Joseph Diller, the purported Old Man of the Lake has been coasting upright from that point forward, remaining around 1.2 meters (4 feet) tall over the surface.
What's more, it's not simply swaying in the one place - in 1902, Diller distributed the principal logical study on the stump, and found that inside the initial five years of its disclosure, it had voyage nearly 400 meters (1,312 feet) through Crater Lake.
A second investigation keep running between 1 July and 30 September 1938 found that it had voyage way encourage that even that - because of high winds and waves, the resilient Old Man had secured no less than 99.9 km (62.1 miles) in only three months.
"You would surmise that the 4-foot over the water would go about as a little sail, however here and there he'll move the distance over the lake against the wind," Mark Buktenica, a sea-going scientist for the National Park in Southern Oregon told Conor Knighton at CBS News.
As the man in the picture underneath illustrates, the uncovered end of the stump may be chipped and blanched by the sun, however it's light and sufficiently wide to bolster a whole individual's weight.

So where did this secretive stump originate from?
Thought to be a hemlock trunk, the Old Man of the Lake has been drifting in Crater Lake in southern Oregon's Crater Lake National Park for at any rate the previous 120 years, however cell based dating recommends that it is no less than 450 years of age.
Hole Lake incompletely fills a colossal 655-meter-profound (2,148-foot) cauldron-like despondency that conformed to 7,700 years prior when the Mount Mazama spring of gushing lava fallen amid a disastrous emission.
The lake itself is nearly 592 meters (1,943 feet) profound, making it the most profound in the United States, and the ninth most profound lake on the planet.
What's especially unordinary about this lake is the means by which generally discharge it is. As per the US National Park Service, fish are not local to the lake, and the species that exist there now were presented somewhere around 1888 and 1941.
Six species were initially presented, yet just two have survived: rainbow trout and kokanee salmon.
The relative vacancy of Crater Lake is really what gives it its mind blowing shading. As the National Parks site clarifies:
"Water particles, out and out water without any silt, green growth, pesticides, or contamination, will ingest every one of the shades of the range aside from the blues. Those wavelengths will skip back and make the water seem blue.
The key is to have moderately immaculate water and bunches of it. There must be sufficient atoms to ingest the various hues. (There are 4.6 trillion gallons of water in the lake, so it works truly well)."
At a profundity of around 120 meters (394 feet), a specific sort of greenery from the Fontinalis family is found to develop, and the main place that this greenery is found close to the surface is on the Old Man of the Lake.
This recommends the log may have had contact with more profound waters in the lake in the course of recent years.
However, how could it have been able to it come to be upright in the water, and how has it figured out how to stay like that for so long?
Fundamental material science expresses that a drifting object of uniform thickness will dependably have its focal point of mass as being higher than its focal point of lightness. That implies a long log will drift with its pivot in a level introduction, and a short log will skim vertically.
Being 9 meters in length (30 feet) with a distance across of around 61 cm (2 feet), the Old Man of the Lake ought to coast on a level plane. So what's making it situate vertically?
Nobody's possessed the capacity to think of an authoritative answer yet, however it's been recommended that when it slid into the lake over a century prior, rocks had ended up tangled up in its underlying foundations. These common stay focuses would have quickly arranged the stump to skim vertically.
The main issue with this speculation is there are no stones joined to the log now, and there's no conclusive confirmation of them constantly having been there, so it's to a great degree hard to demonstrate.
In any case, it's been contended that the submerged end would have ended up denser and heavier after some time as it was drenched through, while the uncovered end remained never-endingly dry.
"This clear harmony permits the log to be exceptionally steady in the water," the Crater Lake Institute clarifies.
Reality behind the Old Man of the Lake may be clouded always, however as National Park biologist Mark Buktenica told CBS, "I'm alright with not knowing."
Glide on, Old Man.
