Ups and Downs

After yesterdays progress, today's was disappointing. During the night, water had seeped into the drill hole and other technical issues slowed down the drilling. Then from about 45 metres below the surface we pulled up an ice core that was dripping with water. We must have drilled into a water conduit in the glacier. We lowered a weighted cord down the borehole and when we pulled it back up about 13 metres of it was wet. The water had flooded our drill hole.



This was very disappointing. We discussed what to do and decided that the next day we would set the drill up for another attempt about 300 metres away, near to an interesting wind scoop on the side of the glacier. This feature is about 70 metres deep and several hundred metres long, where the strong winds have scooped out the snow and ice all around the side of the peak of Mount Annette.
