...The drill continued to drill glacier ice cores down to 3091m - with no
water entering the hole. Our new hole is just 50 cm next to the one from

sized fragments of organic material looking like a pine needles or pieces
of bark. There is a big possibility that this material is several million
years old - from a time where trees covered Greenland. The presence of
plant material under the ice indicates, that the Greenland ice sheet
formed relatively fast, as a slowly growing glacier would have flushed or
pushed these light particles away.
