Speleologists found a possible extension of the cave with remains of mammoths in the Crimea
«Cavities have already been found. A drilling will be performed using a drill of a diameter of 600 mm, to make way for the speleologists. I mean, it could happen tomorrow or the day after tomorrow. This is undoubtedly a unique geological system that is now blocked by clay and dump deposits in places. It was a single system of water-bearing stratum in ancient times», Samokhin said.
The cave can stretch for several tens of kilometres, said the source to the news agency.
