Twenty-five years ago, New Zealand researchers Roy Daniel and Hugh Morgan made an arduous six-week expedition across sea, ice, and snow in search of thermophilic bacteria on the volcanic slopes of Mount Erebus, the world's most southerly active volcano. Erebus rises some 3,660 meters from Ross Island, in the icy oceans near Antarctica. As the two men made their way to within 90 meters of the summit, they battled temperatures that dropped to -35ᄎC (-31ᄎF), with a wind chill that made it feel like -70ᄎC (-94ᄎF).
