The Rough Kulm is a volcano that never broke out. Deep cracks in the earth's crust, which developed in connection with the unfolding of the Alps, made its emergence possible. The dark magma does not come from the earth's crust, but from the upper zone of the mantle from about 50 kilometers deep. On the way up the magma froze before it reached the surface of the earth. After the surrounding rock layers, which mainly consisted of Keuper, were eroded, the exposed basalt columns broke into a debris field around the summit. The Rough Kulm is about 21 million years old. Its present form resembles that of a stratovolcano. The mountain is 682 m high and offers from its 25 meter high observation tower an impressive panoramic view of the Fichtelgebirge, the Franconian Alb and the northern Upper Palatinate. The mountain is one of Bavaria's most impressive basalt mountains. It has geological, nature conservation, historical and tourist significance. At the western foot of the Rauhen Kulms is the small town of Neustadt am Kulm, at the edge of which the rock formation Kleiner Kulm rises to 563 m above sea level. NHN rises. From the summit it is about the same distance to the 511 m above sea level. NHN high Kühhübel in the east. The Rauhe Kulm has been protected as a natural monument since 1949 and is part of the Northern Oberpfälzer Wald Nature Park. The observation tower was rebuilt at the end of the 80s, after the old one was destroyed by arson
