From an old negative. I've at last found my negatives from Mawson (I used two camera bodies, one with slides one with B/W). So I'm going back to the start of the 1966 Spring Trip from Mawson, showing two tractors hauling caravans to the plateau. Once there, the caravans and sledges were organised into trains. The husky pups really aren't hauling anything. :) Minolta SR1 with Adox film, Auto Rokkor 55/1.8.
