At the Valdai lake, located on the territory of the Valdai national Park in the Novgorod region, took a very rare and beautiful winter phenomenon. Fantastic ice crystals covered almost the entire surface of the lake.
Photographs of the natural wonder managed to make the local photographer Timothy Shutoff.
"For such a "blooming" needs a number of conditions: no wind, thin young ice, air temperature below -20° C (and in the Valdai tonight was exactly this) on the ice surface of about 0°C. In this case, the surface of the ice formed is saturated with moisture layer. The moisture collides with cold air, is suddenly cooled and again condenseries on the surface of ice crystals several centimeters. Unfortunately, this beauty is short-lived: when the ice thickness increases, the temperature on its surface approaches the temperature of the air and the flowers will disappear," — said the source.
In the comments of Internet users also admire the photos and call this phenomenon "cotton ice" or even "petrified roses".
"I'm at Valdai about 24 years and, in my opinion, such fields of ice "flowers" on it formed for the first time," says Director of the Valdai national Park Nikolai Sokolov.
