Saturday 17th February

The weather was exceptionally good today, so we decided to take a long ski-doo trip to Walnumfjellet, a group of small mountains located 70 km from Princess Elisabeth Station. For this very technical trip, amongst glaciers leading to the high plateau, we were lucky to have Alain Hubert as our guide, next to Raphael. After a long ride, we eventually reached our destination, 2400 m above sea level and with wind-chill effects reaching -28°C. We quickly noticed glacially eroded summits popping out of the ice, which looked like ideal sampling sites. The cold temperature motivated us to quickly get to work, sampling a very promising looking fine-grained detritus. Promising because the surfaces of these flat summits have been stable and potentially exposed to the sky for approximately 2 million years, during which we surmise that they have been accumulating cosmic dust falling from the heaven. After sampling 5 different sites, we made our way back to the station, through steep glaciers and long stretches of icy flatland. Once back, we couldn’t hold our excitement and started looking through one of the sample. Much to our amazement, we found more than ten micrometeorites in less than 15 minutes, making this sample exceptionally rich. We can finally say that braving the cold and lack of oxygen was a small price to pay for such an exceptional find and day.
