Antarctic Comrades chronicles an American scientist's adventure with a Soviet research team in 1960. This book is Gilbert Dewart's description of the work accomplished at the Mirnyy research station and of a four-month summertime trek inland to Vostok, another Soviet station in the coldest part of Antarctica. It illuminates an event during the Eisenhower/Kennedy/Khrushchev era, an early attempt at glasnost, and the evolution of the international scientific community.
