Last week, the South Pole traverse finished unloading the supply of fuel it had brought, transferring it all to the tanks on station. They should be all set for winter, which is long at the South Pole and is fast approaching. After a pretty busy week wrapping up various activities, all the IceCube folks working at the Pole departed by the week’s end, except for the two winterovers who, of course, remain for … the winter. On Friday, entertainment at the station included some ping pong challenges. The prize? It’s in the fine print: “Your choice: free root canal, or earrings made from YOUR OWN wisdom teeth!!” The challenger? Bob the dentist.
