Kleine Oker Dam Keeper's Cabin and Weir

Highlight • Mountain Hut

Here the little Oker crosses the ditch. For the numerous stream crossings, so-called "failures" have been set up, which prevent debris from being washed into the trench and enable the trench to be cleaned. The HWN 149 stamping point is also here. The small Oker feeds below the Altenau forest swimming pool.

Dammgraben

Highlight • Structure

The Dammgraben is the longest man-made ditch in the Upper Harz and is part of the Rammelsberg Mine, Old Town of Goslar and Upper Harz Water Management and has been recognized as a UNESCO World Heritage Site since 2010.
Its purpose was to divert surface water for the operation of the Upper Harz coal and steel industry from distant areas with high levels of precipitation (in particular from the Bruchberg massif and parts of the Brocken massif). It gets its name from the Sperberhaier Dam, which bridges a depression in the terrain.

Schachtkopf Hut

Highlight • Mountain Hut

The hut has a typical resin construction. Hikers can easily assert themselves in bad weather. In front of the hut there is a small rest area right next to the Harzer Hexenstieg and the Dammgraben.
