Метеоритное происхождение кратера было подтверждено в 80-х годах
московской Комиссией по метеоритам и космической пыли СО АН СССР,
возглавляемой Юло Кестлане из Эстонии.
This structure looks like a funnel (see the topography map) with a
small lake in the center and is named by natives as "Yama
Korchazhikha", its diameter - ca 200-300 m, coordinates: 52,183 N,
106,767 E. Not far from it (< 1 km), the second smaller funnel
locates (d~20m) that has more clear and expressive section profile. Its
cosmic and impact origin was confirmed by a special Moscow meteoritic
commission headed by Dr. U. V. Kestlane of the Estonian Academy of
Sciences in the 80-s, but for a long time those materials were fogotten.
According to spoken message of U. V. Kestlane, the age of this
structure can be supposed about 80-100 thousands years and its origin is
purely of impact. His assumptions is based on the geomorphology of
structure.
