Subfossil wood in Zurich

Im the summer of 2013, WSL researchers found 257 pine stumps on a building site in Zurich's Binz neighborhood on the foothills of the Uetliberg.

At first glance, they look like any old tree stumps, yet they are causing a scientific sensation. What is remarkable about them is their age: the pines grew over 13,000 years ago, just after the retreat of the great alpine glaciers. This makes this substantial and well-preserved discovery the oldest of its kind - and the world's largest for late-glacial trees.

Over the next few years, scientists will be using them to gain valuable insights into the climatic conditions in Switzerland at the end of the last ice age.
