At 927 m above sea level the Bruchberg in the Upper Harz is the second highest mountain in Lower Saxony and the third highest in the Harz mountains in North Germany. It lies between Altenau and Torfhaus in the middle of the Harz National Park. The Bruchberg is more like a plateau and has no real summit. This plateau is partly covered with trees, but on the sunny southern slopes the trees have largely died as a result of bark beetle infestation. Following this insect destruction, a new natural forest, rich in its variety of species, is now growing in the heart of the Harz National Park.
The Wolfswarte, at 918 m above NN, is generally considered as the summit, even if it is not the highest elevation on the Bruchberg. It is a domed hilltop (Kuppe) made of weathered Acker-Bruchberg quartzite. The Wolfswarte rises east of the mountain town of Altenau and, in good visibility, the Brocken can be seen from here. The bald summit of the Wolfswarte is easily visible from other peaks in the area, notably the Glockenberg in Altenau, the Schulenberg and also from the Torfhaus.
