Yesterday (May4) was the coldest day so far, -23°C in the morning with temperatures reaching -17°C in the afternoon. Beautiful weather with NNW wind and heavy skiing conditions. The so-called sand-paper snow that many polar explorers know was problematic because snow becomes stiff and skis stop gliding in temperatures below -20°C. It was hard work to ski over 16 km in 6 active hours and 30 min. At 18:00 when they put up their camp the wind started to blow harder requiring shelters for the tents. Today strong winds are forecasted and they do not plan to wake up early and see what the day brings. Again, everyone is in good spirits.
