I found a maybe more precise description of the history and geology of the Luneburg Heath:
"The Lüneburg Heath is an area in Northern Germany which was formed and marked by the ice age. The rivers Elbe and Aller form the boundaries of this part of the so-called „Geest“. The Lüneburg Heath is a lowland the height of which ranges from less than 50 up to 169 metres above sea level. For several milleniums, the main feature of this landscape used to be the heather (Calluna vulgaris). But over the last century, the main feature of this landscape changed its character almost everywhere. Only a small part in the north-west of the area, the region around the wellknown hill „Wilseder Berg“, has nearly kept its original appearance: Extensive heathland lends the landscape its character, and a special breed of sheep is put out to pasture here: the so-called „Heidschnucke“ which is descended from the „Mufflon“ (Ovis musimon). The wool of this ancient breed is said to have been found in the burial mounds of the Bronze Age which are more than 3000 years old. Another important domestic animal was and is the honey bee, which is partly still kept in Naturschutzpark, a private association concerned with nature conservation."
Fondest memory: I found this nice webpage, where you can get this and more information in English:
Favorite thing: The last glaciers of ice age (around 12.000 years ago) left lots of sand and swamps in Northern Germany. In the last few years it was discovered, that already people of the late stone age build small roads through the moors. To trade between the North See, the Baltic See and central Europe, the traders had to cross the Lueneburg Heath. Salt was one of the main goods traded. The city of Lueneburg was the center of the salt trade and became a very wealthy town during the times of Hanse.
Favorite thing: The Lüneburg Heath is the result of extensive deforrestation in medieval times, when the forrests were cleared for firewood for salt production in Lüneburg. After clearing the forrests shephards brought their heards here. The sheep ate the gras and new growing trees, so that there developed an open area covered with heath, gras and junipers and some birch trees. Since the last century sheep are not used any more. That means for the Lüneburger Heath, that forrest trees are coming back and destroy the special character of this area. In the Nature park Lüneburger Heide are some sheep held to conserve the last spots of heath.
Favorite thing: Walking on the small paths not far from the Hotel Tütsberg I discovered this lovely old building. It looked as if it has been renovated to be a holiday home for somebody now. It was just in the middle of nowhere, far away from any bigger road. It must be very relaxing and quiet to stay here for holidays.
