Kahler Asten (Germany)

Weather…

The Kahler Asten, standing at 841.9 meters, is the most renowned peak in the Rothaargebirge, situated in the Hochsauerland region of North Rhine-Westphalia. Although frequently cited as the state's highest mountain, it is slightly exceeded in height by the Langenberg. The summit area is defined by an extensive highland heath, designated as a nature reserve of European significance, hosting rare species such as dwarf shrubs and bilberries. Geologically, the mountain is composed of graywacke and clay shale dating back to the Devonian period, roughly 400 million years ago. At the peak stands the Astenturm, an integrated facility containing an observation tower, a weather station, and a restaurant, with its foundation stone laid in 1884. The Kahler Asten also serves as a critical watershed, being the source of several rivers including the Lenne, which later flows into the Ruhr. The climate is harsh, characterized by high precipitation levels and an average snow cover of over 70 days per year.
