Königslutter is a town in the northern part of the Harz region of West Germany. During the last two ice ages this area was covered by a thick layer of ice, but the Harz Mountains prevented the ice from moving any further south. As a result, this area is rich in boulder clay and large erratic boulders brought here by the ice from Scandinavia. South of Königslutter there are no more large boulders, because they could not get over the mountains.

A large part of the Harz is now a geopark (Geopark Harz – Braunschweiger Land – Ostfalen), just as the Hondsrug region. One of the Geopark projects in the Harz is the Königslutter Boulder Garden (Findlingsgarten), which lies in woodland and can be reached by a short well-signposted walk (see map below).

The Boulder Garden (Findlingsgarten) is clearly signposted from the car park.

It consists of a collection of erratics found in the immediate area and brought together in one place. There are many Indicator Boulders (stones which can be identified as having come from a specific place). From these it is possible to establish the precise flow of the ice during the ice ages.

The boulder garden is in a natural setting in the middle of woodland.

A nature walk has been laid out in and around the boulder garden
An unusual flint measuring 50 cm with a hole in the middle. There are a number of remarkable boulders in the garden such as this enormous flint measuring 50 cm with a hole in it. This once sat at the bottom of the sea where chalk was deposited. Shellfish such as crayfish bored holes in the soft chalk and this flint later formed around a central core. When the chalk had weathered away, this flint was left. Later it was brought here by the ice and deposited in the Harz. It probably originated in the area around North Germany, Rugen and Denmark.
This sandstone with fossilised wave ripples from an ancient sea is approximately half a billion years old.
There are many different types of gneiss and granite from Scandinava.
