Hostile conditions in Antarctica make scientific research rather difficult, so most scientists rarely visit the 7th continent, instead using satellite data to complete their work. But sometimes even scientists are baffled when they find structures on satellites pictures they cannot explain right away.
That happened when scientists got hold of a picture that showed something that appeared to be a crash site forming long stretch in the ice. Aviation experts agreed that it could be formed by something landing there and skating to a halt. This theory wasn’t completely out of the blue since the site where this picture has been taken from is quite close to the incident site of one of the world’s worst aviation accidents when a passenger aeroplane crashed into Mount Erebus back in 1979. But the theory couldn’t hold for long once the shadows of the shown objects got taken into consideration and NASA scientists revealed an unusual type of glacier forming a seven-mile-long wall of jagged ice on the frozen sea of McMurdo Sound.
