When the sea-ice off Mawson research station can no longer support planes, expeditioners move the landing area 20 kilometres inland.

The mission involves a small convoy of Hägglunds snow tractors and a four-tracked heavy hauler travelling up the ice plateau to prepare for an intra-continental flight.

The landing area near Rumdoodle Hut is a flat expanse of ice sheet that’s been used for aviation since the 1960s.

The field hut at Rumdoodle was refurbished this year by the winter team of Mawson expeditioners.
