The Steile Wand (literally "steep wall", or "steep face") is a 518.9-metre-high (1,702 ft) hill ridge in the southwestern part of the Harz Mountains in the German state of Lower Saxony.

The Großer Mittelberg (the short form Mittelberg is also common) is a ridge in the Harz Mountains of Germany that begins immediately northeast of Lonau in the district of Göttingen in Lower Saxony. It separates the valley of Kirchtal, through which the Große Lonau flows, from the Mariental and the Kleine Lonau. is Although it is the nearest subpeak to the village of Lonau, the Großer Mittelberg is, at 531 metres, not the highest point, but may be viewed as a main summit due to its prominent location. From here on, the ridge only climbs gently in a northeasterly direction and has several more subpeaks with small wind gaps. To the north the Großer Mittelberg transitions to the ridge of Auf dem Acker without any noticeable wind gap. The Großer Mittelberg is almost entirely covered in beech woods and lies within the Harz National Park.

The Franzosenkopf is a 562 metre high hill in the Harz Mountains of central Germany, which lies about 1.4 kilometres northeast of Lonau in the district of Göttingen in Lower Saxony. To the north of the Franzosenkopf is the Braakberg, a shallow saddle separating them. Flowing around the Franzosenkopf to the east and south is the Kleine Lonau in the valley of Mariental ("Mary's Valley"). To the west the Franzosenkopf is separated from the Kargeskopf hill by the Hackenstieltal valley. The Franzosenkopf is mostly covered in beech, but spruce also occurs in places. It lies entirely within the Harz National Park.

The Höxterberg is a hill in the Harz Mountains of central Germany, that lies south of Sieber in the district of Göttingen in Lower Saxony. It is 584 metres high and lie 0.9 kilometres west of the Pagelsburg, 1.5 kilometres south of the Fissenkenkopf, 1.8 km west of the Großer Knollen and 1 kilometre north of the Mittelecke. The hill is mostly covered by beech woods. Towards the northwest the Höxterberg transitions into the Steile Wand.

Kleine Lonau is a tributary of the Große Lonau in Lower Saxony, Germany. It rises at a height of 650 metres and flows through the Mariental valley to Lonau, where it merges with the Große Lonau. It is about 4.2 km (2.6 mi) long.

The Fissenkenkopf is a hill in the Harz Mountains of Germany, that rises south of Sieber in the district of Göttingen in Lower Saxony. It is 527 metres high and is the western extension of the Adlersberg and the Kloppstert hills.

The Eichelnkopf is a 545.7 m (1,790 ft) high hill in the southwestern part of the Harz Mountains in the central German state of Lower Saxony.

Lonau is a small village with a population of about 345 situated at an elevation of about 400m in the Harz Mountains of Northern Germany. Besides the clean air and lush forests, it is famous for the capercaillie. It belongs to the city of Herzberg am Harz which is about 4 km to the south. The rivers Große Lonau and Kleine Lonau join here.

The Braakberg is a 645.5 metre high mountain in the Harz in central Germany, in the unincorporated area of Harz in the district of Göttingen in the state of Lower Saxony.

The Kloppstert is a hill, roughly 553 metres (1,814 ft) high, in the southwestern Harz in Lower Saxony, Germany. In the topographical map printed in 1978 it can only be made out with difficulty that the third letter is an o and the penultimate one an r. However, a contour line runs over the letter r so that it looks like a p. In the digitalised 1:25,000 topographic map, the hill is wrongly named as the Klappstept.

Tiefenbeek (also Breitentalbach) is a small river of Lower Saxony, Germany. It flows into the Sieber in the village Sieber.

It is 593.2 m high and is situated west of the Aschentalshalbe. It also separates the valley of Breitental ("wide valley") with its river, the Tiefenbeek, from the Langental ("long valley"). To the northwest the Adlersberg transitions to the Kloppstert and the Fissenkenkopf hills. Other nearby peaks are the Pagelsburg 1.2 km south, the Höxterberg 1.6 km southwest and the Großer Knollen 1.9 km southeast.
