In parallel, Hillary's team had set up Scott Base—which was to be Fuchs' final destination—on the opposite side of the continent at McMurdo Sound on the Ross Sea. Using three converted Ferguson TE20 tractors and one Weasel, abandoned part-way, Hillary and his three men—Ron Balham, Peter Mulgrew and Murray Ellis)—were responsible for route-finding and laying a line of supply depots up the Skelton Glacier and across the Polar Plateau on towards the South Pole, for the use of Fuchs on the final leg of his journey. Other members of Hillary's team carried out geological surveys around the Ross Sea and Victoria Land areas.
