A special natural phenomenon in Amt Neuhaus: the Stix shifting sand dune.
The Stix shifting sand dune has a size of about 9.5 ha. It was formed about 10,000 years ago after the Ice Age and is the remnant of a dune landscape from Preten to Wehningen that was once largely determined by drifting sand. It is one of the most important natural monuments of the region. To this day, large pine trees here are blown up to the top with sand and also uncovered again. The dune is still in motion, it "wanders". Reindeer lichen, silver grass, beach grass and heather make up the sparse vegetation.
Numerous rare animal and plant species, which have adapted to the special living conditions, find their home here. From the top of the dune there is a magnificent panoramic view of the Elbe floodplain. The color contrast between the almost white dune sand and the dark green pines is impressive.
