Relentless Nature at Work in Antarctica 
National Science Foundation Posted July 27, 2018 High winds drove snow and battered NSF’s Amundsen-Scott South Pole Station during a streak of Antarctic bad weather that lasted for weeks in June. One storm in particular formed a gigantic sastrugi, or snowdrift, nearly as hard as concrete, by pushing snow through the closed doors of the station’s logistics arch, “one snowflake at a time, over the course of a single weekend,” according to Raffaela Busse, a particle physicist with the IceCube Neutrino Observatory, who is spending the Southern Hemisphere winter at the Pole. The sastrugi, which was roughly three meters (10 feet) tall, was cleared way by hand…only to have another pile up a week later.
