"[2] Mostly fed by snowmelt from mountain streams, the lake freezes in November and stays icebound until April.

The Krutik, Marin and Nazarychev peninsulas extend into the lake.

[2] On 15 February 2013, local fishermen found a hole in the ice where a large fragment from the 2013 Russian meteor event likely struck the frozen lake.

[6] In the days after the impact, black fragments of rock were found around the hole, which scientists from Ural Federal University suspect are meteorite fragments, and composed of about 10% iron.

[7][8] Months later, divers found a large meteorite fragment on the lakebed, and it was dredged to the surface on October 16, 2013.
