Snowtrac on the slope

Copied from an old 1966 slide. Snowtrac vehicle fitted with experimental sounding equipment (the booms either side) for measuring the ice thickness. View looking north over Mawson (below the brow of the ice, just right of the vehicle) and showing the relative steepness of the climb to the plateau. Also on skis our glaciologist, who was able to use them like skates on the hard blue ice!
