| Still windy, but towards evening the wind speeds decrease. |
| Science |
| There is not so much tar left in the borehole - but still problems.
It is concluded that it must be the high pressure and warm temperatures
at the bottom of the borehole that causes the ice chips to sink instead
of raising in the borehole liquid. Drill depth: 2846,65 m |

| The highlight today was a wild snowscooter race. While starting a snowscooter
the gas trottle was stuck and the scooter moved with full speed in a circle
with a radius of 1 km. A trackvehicle tried to catch the wild scooter without
luck. A bump released the trottle and the show ended without damage to
rider or scooter. |

| Science |
| Today the worst thing possible happened for the drilling: At 6 pm the
drill got stuck at a depth of 2930.55 m. During the day the bore hole had
been cleaned for ice cuttings, and later an ice core was drilled routinely.
During drilling of the second ice core the drill stopped after drilling
about 1 m of core, and the drill was stuck. The cable was pulled with a
force of almost 2 tons (4400 lbs), but the drill was not released. The
drill cable was left overnight with a tension of 1.4 tons (3000 lbs) in
the hope that the drill could be recovered before Monday. |
