Next month marks the 100th year since the first Antarctic expedition reached the South Pole. (Congratulations, Mr. Amundsen.) This week Science Friday talks with the authors of two books about those famous first expeditions. Edward Larson’s Empire of Ice reexamines the voyages of Robert Scott and Ernest Shackleton. (Scott took second place to rival Amundsen; Shackleton never got to the pole.) In The Lost Photographs of Captain Scott, David M. Wilson has gathered photos from Scott’s expedition. Grab a sweater and click below to see the stark polar landscape that Scott and crew (including photographer Herbert Ponting) encountered. Brrrrr.
