In this Sunday, Jan. 20, 2013 photo, U.S. research personnel from McMurdo Station scale nearby Castle Rock for recreation on Ross Island, Antarctica. Tourism is rebounding here five years after the financial crisis stifled what had been a burgeoning industry. And it’s not just retirees watching penguins from the deck of a ship. Visitors are taking tours inland and even engaging in “adventure tourism” like skydiving and scuba diving under the ever-sunlit skies of a Southern Hemisphere summer. (AP Photo/Rod McGuirk)
