From an old 1966 slide. The major field trip away from the station was the Spring Trip, here seen at its first stop. This was to the northern Prince Charles Mountains and involved seven of us surveying previously unvisited mountains, some 300 km inland - we were away for four months. Everything was moved in caravan trains, drawn by D4 bulldozers. Only a short distance inland, the blue ice seen at the edge of the plateau gives way to compacted snow, carved by the wind into waves known as "sastrugi", as seen here.
