Spiertin 07: Höckriger Zeuge

In front of you you will see a round hump. It is one of the typical landscapes created by glaciers. Thanks to such typical shapes as these humps, you can also know far away from today's glaciers where a glacier once was.
In the audio, Spiertin tells you how such round humps are created. The audio file can be found at the back of the pictures.
