In the northern Harz foreland between Ballenstedt in the east and Blankenburg in the west, steep, sometimes meter-high sandstone cliffs form an imposing natural phenomenon over a length of approx. 20 km, which is known as the Teufelsmauer. The rugged, erosion-resistant cliffs are formed by layers of silicified sandstone, the formation of which is associated with the uplift of the Harz Mountains and their overthrust to the northern foreland during the Upper Cretaceous. The Königstein, Mittelstein and Papenstein sections south and south-west of Weddersleben have been under nature protection since 1935. In 2006, the Teufelsmauer was awarded national geotope status and is now an important geopoint in the UNESCO Geopark Harz – Braunschweiger Land – Ostfalen. … Continue readingThe Devil’s Wall at Königstein

If you head to the east from Leipzig, you will encounter one of the largest areas of volcanic rock in Central Europe – the Northwest Saxon volcanic complex. At its southwestern tip lies the Rochlitz mountain, which cleary stands out from the surrounding landscapes with a height of 353 m. … Continue readingThe Gleisberg quarry

The “Lange Wand” is like a window into Earth’s history: from the Ilfeld porphyry (280 million years) to the copper shale and the Zechstein limestone (250 million years). In the mine of the same name, copper shale has been mined since the 16th century. Here, in addition to cobalt ore and barite, you can also admire fish fossils, the so-called “copper shale herring”. … Continue readingThe “Lange Wand” (long wall)

The Schneckenstein is a well-known topaz rich outcrop located in the identically named district of the town of Muldenhammer in Saxony. The outcrop rises 23 metres above the ground in a mostly flat surrounding. With a height of 883 metres above mean sea level, the Schneckenstein is one of the highest points in the Upper Vogtland area. For protection purposes, the rock itself and its surroundings are fenced and can be visited during opening hours. On the 5th November 1938, the Schneckenstein was named a natural monument and added to the Saxon geosite list as number 259. The Schneckenstein is part of a joint geological research project of Topaswelt Schneckenstein, TU Bergakademie Freiberg and the Vogtland Geoumweltpark. … Continue readingThe “Schneckenstein”

Beneath the town of Freiberg in Saxony exists a large underground mining system dating back to the 18th century. During construction work at the Untermarkt in 2018, the so-called family mineshaft (German: “Familienschacht”), which was used to mine silver, was rediscovered. Due to the visit of Alexander von Humboldt, the Familienschacht is also known as the Humboldt Shaft. For safety reasons, the mining system is not accessible to the public. However, a 3D model was created to enable visitors to experience it. … Continue readingThe “Familienschacht”
