Stubbergård lake - Flynder lake

Tunnel valley. Meltwater valley with dead ice holes.
Helmet Heath

In the Danish landscape, examples of complex landscape forms as a result of at least two glacier crossings are found almost everywhere.

Stubbergård Sø – Flyndersø presents a very educational example of the fusion of two landscapes and is at the same time a site that also conveys the tunnel valleys of the geopark. The site encompasses a widespread area of poor relief east of Venø Bugt, characterized by elongated lakes, and numerous small lakes and bogs.

The heath plays a major role in the local self-understanding and the death holes in Hjelm Hede have inspired many local legends as well as a scene in a story by one of Denmark's important authors: Jeppe Aakjær (1866-1930), who was an important communicator of the harsh living conditions in these parts.

The dune sand rests partly on glacial deposits and partly on raised seabed. The glacial deposits can be observed in the cliff profile at the western boundary of the area at Græm Klint , where it is clearly evident that the glacial layers are covered by thick aeolian sand deposits.

The coastal dunes are located on a stretch of coastline that is undergoing erosion, and in several places along the West Coast there are active dunes with exposed sand surfaces.
