RECORD OF SNOW VEHICLE KD 605 USED FOR THE JARE SOUTH POLE TRAVERSE IN 1968-1969
Three snow vehicles, type KD60, were successfully used by the traverse party of the 9th JARE (Japanese Antarctic Research Expedition) which made a round trip along 43°E in longitude from Syowa Station to the South Pole (direct distance : 5,180 km) during a period from September 1968 to February 1969...
