Looks fake,there are no frozen fish,and also if sun is shining on that ice so hard that we can see stones under it,why didnt it melt ,and why is there no sound of mountain wind ?

the lack of fish can be explained by the fact that slovakia is directly in the dead zone caused by german (and russian) industrialization. clear lakes like this are a common result of acidification caused by acid rain.

There are no fish in lakes that high.

as a broad statement, that's just simply not true, although i have to admit that i'm not aware of the exact level of biodiversity in the slovakian mountains. while you may see specific adaptations or localized populations in specific areas, it is broadly true to state that some type of fish or another can survive at just about any altitude.

The ice in the video is an example of congelation ice, which is also known as black ice because of an ability to see through to the color of the water underneath. The congelation ice forms underneath an existing layer of ice, building off of the bottom. When the top layer is melted, the crystal-clear layer is revealed. The incredible clarity of the ice is a result of freezing with no air bubbles, snow, and impurities present. When impurities or air bubbles are trapped in ice, it causes the light to scatter as it travels through and results in a cloudy appearance.

i think you're half right - the explanation of the mechanism is correct, but i don't think these conditions can be observed nearly as dramatically in a normal, healthy lake.

The water isn't tainted as well, and it looks like the water is completely frozen through, making it clear. You can tell because of the refraction of light, if there was water underneath, the light would change it's course through water, ice and oxygen.

i think what i'm reacting to is the misperception that the world is "clean" unless humans touch it. that perception is going to create the idea that water in untainted sources is crystal clear. but, in fact the opposite is true - the natural world is a very dirty place, partially because it is full of life. it only becomes "clean" when we modify it.
water running through a stream is getting filtered, but "untainted" lake water is generally pretty dirty. sulfuric acid , however, is a pretty strong cleanser. that's why dead lakes are so clean looking.

What do u have got with that "healthy lake" "Czechoslovakia" and "acid rain" ?
That lake isn´t healthy because it's +-2000 meters above sea level then there aren´t fish, plants and who knows what else. Czechoslovakia doesn´t exist since 1993 (now is Czech republic or Slovakia/Slovak republic), and that acid rain....I don´t think so that we have got acid rain in High Tatras. and from SOUTH Germany and from Russia ???? WTF ??? Those countries are far away except Germany,that is closer, but not so much.
(Sorry for my english I´m still learning.)
deathtokoalas
yes, the tatras are one of the worst acid rain regions in the world, due to the effects of emissions from neighbouring regions. this is well understood. generally, acid rain falls a little bit away from it's emission source. the acid goes up, travels a bit through the air and then comes back down again.
it was a long time ago, but let me think back to what i remember learning about acid rain in the third grade.
1) acid rain is primarily caused by a reaction of sulfur dioxide and nitrogen oxide inside of clouds, which falls as sulfuric acid and nitric acid.
2) the sources of sulfur dioxide and nitrogen oxide are mostly factories.
3) canada's acid rain problem is largely caused by heavy pollution floating northwards from the area now known as the rust belt. pollution from heavy industrial areas like detroit and cleveland enters the atmosphere, moves north and falls in ontario, where it kills trees and creates dead lakes.
4) eastern europe also has a substantial acid rain problem, with the worst hit areas being poland, sweden and czechoslovakia (as it was then called, for a few more years). this is also caused by emissions moving into the region from neighbouring industrialized areas - primarily the heavily industrialized regions of germany. i distinctly recall learning about damaged statues in poland and dead lakes in sweden. this was presented as a test case, and a warning of what might happen in canada if emissions are not reduced.
as it turns out, the rust belt collapsed as a result of nafta, and emissions did decrease. europe took a more pro-active approach.
however, the effects of acid rain continue to linger in the region. again: if you don't believe me, look it up.

ugh.
"Congelation ice is often referred to as black ice because it has a high optical depth that permits significant light transmission to the underlying water."
once again: you've explained why you can see through the ice. you haven't explained why you can see through the water.
somebody really ought to ddos the lot of these pop science sites. they post garbage.
black ice is black. or at least looks black. because of the water.
normally, you wouldn't be able to see through a body of water with a layer of black ice on it. rather, it would create a reflection of the surrounding area.
