As time goes by...

The soil on which you stand is geologically very young and belongs to a moraine formed by a glacier. Like all of Zurich, the Irchel area was shaped by the ice ages. The last Ice Age began over 115,000 years ago and lasted until 11,700 years ago. During this time, the area of Zurich was underneath the mighty Linth glacier. When it melted about 20,000 years ago, Lake Zurich was created.
