Success! We finished drilling at Cape Armitage reaching a total depth of 1.2 m in two holes (90 cm + 30 cm). We were extremely exhausted since we finished drilling at 3am in the morning, but very satisfied. Even though the temperature did not drop below -10C a windchill making it feel like -20C .
We had no problems drilling, a few times we hit a hard rock so it took a while for IB to break through – increasing the percussion rate from 800 bpm to over 900 bpm helped.
The same day we packed the drill and delivered all the boxes to helops (short for helicopter operations) for our flight out to University Valley scheduled for 10am tomorrow.
In the mean time we got a new layer of snow. Check out McMurdo’s fresh look…
