The fuel arch under the station (image above) is one of the coldest—and creepiest—places at the Pole, accessed from a network of underground ice tunnels. The tunnels maintain an even temperature of around -50 °C at all times. Guess you don’t really need a thermometer then, but the one in the image below is sitting on a frosty shelf in an ice tunnel. Shelves carved into the tunnel walls showcase a variety of items left behind over the years, some of which can be seen here, from a tour by previous winterovers. Last week’s weather saw whiteouts and winds, harbingers of winter at the Pole. But visibility was still good enough for keeping out of the dinosaurs’ way.
