Antarctica

Most of the story is centred around McMurdo Station, the largest settlement in Antarctica, which is run as a scientific research station by the United States. Robinson's characteristic multiple-protagonist style is employed here to show many aspects of polar life; among the viewpoints presented are those of X, an idealistic young man working as a General Field Assistant at McMurdo; Val, an increasingly embittered trek guide; and Wade Norton, who works for the Californian Senator Phil Chase (Wade and Phil also appear in the "Science in the Capital" trilogy). As well as McMurdo, the story involves the Amundsen-Scott South Pole Station, the Shackleton Glacier, the McMurdo Dry Valleys and a South American drilling platform near Roberts Massif.
