Formerly hidden under a Swiss glacier, a 10,800-year-old tree trunk was discovered, which says the Alps were much warmer in the early Holocene than they are today.
Online SRF Swiss Broadccasting recently reported on a fascinating find in the Swiss Alps: a more than 10,000 year old tree trunk that until recently had been buried under the Morteratsch Glacier.
The professor emeritus of the University of Bern, Christian Schlüchter, says that 10,800 year old larch trunks found under the glacier Alps had to be 10,800 years warmer than they are today. Image: cropped by EIKE.
In 2018, the renowned Swiss geologist Christian Schlüchter received a hint from the local forester about the exciting find that the retreating Morteratsch Glacier had uncovered. However, this specimen was unusual in that it was about two meters long and contained the rhizome. In addition, it was amazingly intact and even contained some bark.
The SRF site contains photos.
The unusually good condition of the larch trunk meant that it was not allowed to be transported down from the glacier and not be ground. This means that the rest area had to be very close to where it originally grew.
The SRF reported:
"It's unique," says Schlüchter and has never discovered anything like it in the Alps. In the case of wood finds, there is always one central question: "How far did the trees grow from the location, how far did the glacier transport them?"
A tree in this condition must have been in the immediate vicinity, otherwise the trunk would look different, says Schlüchter. "
Schlüchter, professor emeritus at the University of Bern, has been working with glacier wood for decades.
Lived 337 years ago 10,800 years ago
According to Schlüchter, the original larch tree lived 337 years before his death and the glacier buried him. Research shows that the larch began to grow around 10,800 years ago, less than 1000 years after the end of the last Ice Age.
The finding shows that there used to be forests in which there are glaciers today, which means that the "Morteratsch Glacier used to be much smaller than it is today," reports the SRF. The region was obviously warmer than it is today.
Rapid climate change 10,500 years ago
Schlüchter also points out that there were larch trees there barely 1000 years after the end of the Ice Age. Schlüchter says: "That shows the incredible dynamic that we see here."
Further studies will be carried out on the tree specimen and parts of the large trunk will in future be exhibited in the museum in Pontresina, writes the SRF.
Christian Schlüchter is Professor Emeritus for Quaternary Geology and Paleoclimatology at the University of Bern in Switzerland. He has authored / co-authored over 250 articles.
