One of the sledges now decides to roll onto its side, tipped over by a snow drift. It takes a while to pull it upright and set off again. I hope that does not happen too much on this journey. We soon pass beside Sloman Glacier which generates a bitter wind, as the heavier cold air sinks down to the lower ice platform where I am travelling. Wind chill really bites here.
Today feels cold, much colder than yesterday.
We push on knowing that we need to be able to travel through McCallums Pass in good visibility to get home safely. The alternative would be a cold camp, and storms are coming, as they inevitably do here. Everything is cold, except our hearts and our souls. I feel warm inside my clothing, but only just. An inch away is an environment that will kill me if I did not have good insulation.
