researchers from prague is being hosted by the institute of applied ecology of the north in the republic of soka. the researchers have just returned from a crater that is carved into the permafrost. these soil samples are a gift to the institute but. in return the researchers hope to obtain permission to exhibit some of their spectacular finds in a museum at home remains of a mammoth and the mummified remains of an extinct horse from the pleistocene epoch you. fear. they will do this if they were. in the crater in which the fossilized remains were found was named the bottom gaika crater but locals call it the gateway to the underworld. it's easy to see why. in the 1960 s. a small section of forest was cleared to make way for a new road. the problem frost originally beneath the trees began eroding. at 1st the hole was just a few metres deep. the student on average the make a crater is between 40 and 60 meters deep and in some places it's 100 meters deep it's 1.5 kilometers long and about one kilometer wide right now but it's hard to determine exactly how wide it is because it's expanding so quick
