The Saalian Ice Age came to an end hundreds of thousands of years ago. The ice melted. Enormous volumes of water searched for a way to the lowest point. On the east side of the Hondsrug a wide river of meltwater formed. This river – the ancient Hunze you might call it – came from the southeast, from Twente and from Munsterland in Germany. At that time you would have been standing forty metres lower than today. The surface of the river was many kilometres wide.
Sand dunes along the Hunze near Spijkerboor
In the second half of the last ice age the permanent cold turned the landscape into a barren waste land. The Hunze valley was mostly dry. Polar winds drove the sand over the surface. In some places here on the edge of the Hunze valley the wind blew the cover sand up into high dunes. You can still recognise the word ‘dune’ in the name Duunsche Lands.
You can also still see from the shape of the dunes that the wind mainly blew from the southwest. They stand in the form of a horseshoe with the open end towards the southwest. The official name for this is a parabolic dune.
