The Patomskiy crater (also Patomsky crater , Russian кратер Патомский , English Patom crater, Patomskiy crater ) is a crater-like structure in Patomhochland in Rayon Bodaibo , oblast Irkutsk , Siberia . The structure was discovered by geologist Vladimir Kolpakov in 1949 .

The structure has a diameter of 180 m and a height of 40 m. Scientific expeditions took place in 2006, 2008 and 2010. Dendrological examinations indicate an age of 480 years or more. The mass of the rocks thrown up is estimated at around one million tons.

The findings point to a volcano that could have been created by steam and gas eruptions. In particular, according to the results of the fifth expedition, it could be cryovolcanism from the Little Ice Age .
