Uh uh, They found the Lost City of the Elder Things in Antarctica!

Why the Great Old Ones haven't destroyed the planes of the survey of East Antarctica by WEGAS (West-East Gondwana Amalgamation and its Separation) is beyond me.

Such formations are inconsistent with meteorite impacts, which generally leave a single crater with a raised center. And as a general rule, these craters also measure between ten to twenty times the size of the meteorite itself – in this case, that would mean a meteorite 200 meters in diameter. This would mean that, had the ring structure been caused by a meteorite, it would have been the largest Antarctic meteor impact on record.

It is clear that it is the Lost City of the Elder Things. If they keep trying to pry into these things they will glimpse the city that even the Elder Things fear. The City that caused Danforth to lose his sanity in H.P. Lovecraft's "At the Mountains of Madness." That place is known as the hated and accursed Plateau of Leng where ululating horrors from out of time lurk and plot to destroy mankind. If they merely glimpse this fortean place all the peoples of the earth will be lost! Pry not into the rime-stained hills from lost and ancient times for they only lead to madness and death!
