X-SCITECH New pyramid in Antarctica? Not quite, say geologists By Laura Geggel November 29, 2016 / 4:21 PM EST / Livescience.com An Antarctic mountain with a unique, pyramid-like shape is suddenly internet-famous, with countless theorists contemplating its origin. Some are wondering whether an ancient civilization created the rocky, pyramidal structure, and others are pointing toward outer space, speculating about the involvement of aliens. But Occam’s razor — the idea that the simplest explanation is usually the right one — points to a far more mundane cause: Those steep, pyramid-like sides are likely the work of hundreds of millions of years of erosion, experts told Live Science. “This is just a mountain that looks like a pyramid,” Eric Rignot, a professor of Earth system science at the University of California, Irvine, told Live Science in an email. “Pyramid shapes are not impossible — many peaks partially look like pyramids, but they only have one to two faces like that, rarely four.” [Photos: The World’s Weirdest Geological Formations]
