Stunning Iridescent Clouds Captured In Rare Sighting on Siberian Peak

The Altai were formed during the great orogenic (mountain-building) upthrusts occurring between 500 and 300 million years ago and were worn down, over geologic time, into a peneplain (a gently undulating plateau with generally accordant summit heights).The mountain range itself is majestic, but the sights that can be seen in Siberia's Switzerland, as it is lovingly called, are unlike anywhere else in the world.
