At , the Achtermannshöhe (also just called the Achtermann) in the Harz National Park is the third highest mountain in Lower Saxony and the fourth highest in the Harz mountains. It lies in the unparished area of Harz between the Harz-Heide route (B 4) and the old Inner German Border about 6 km north of Braunlage. Its summit, covered with loose boulders, stands proud of the surrounding trees and offers a superb all-round view. Equally its characteristic rounded hilltop or ''Kuppe'' is visible in good weather from many other points in the Harz. The Achtermann may be accessed by paths leading from Oderbrück and Königskrug. == Geology == The base of the Achtermannshöhe is part of the granite massif of the Brocken, which extends across a wide area between Wurmberg, Torfhaus and Elend. By contrast, the rocky, treeless ''Kuppe'' of the Achtermann comprises hornfels, a contact metamorphic rock. The hornstone on the summit has a depth of about 10 m and was formed from Grauwacke as it was heated during the intrusion of granitic magma. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Achtermannshöhe」の詳細全文を読む スポンサード リンク
