[[Geomorphological]] processes have led to the formation of [[caves]] in the [[gypsum]], [[Dolomite (rock)|dolomite]] and [[limestone]] layers of the Harz. These [[:wikt:dripstone|dripstone]] caves include [[Baumann's Cave]], the [[Unicorn Cave]], [[Hermann's Cave (Harz)|Hermann's Cave]], the [[Iberg Dripstone Cave]] and, on the southern edge of the Harz, the [[Heimkehle]].
Because the older formations contained many [[mineral deposit]]s, they were explored very early on by the mining industry. The mines have often been turned into [[show mine]]s. For example, the [[Samson Pit]] was for a long time the deepest mine in the world. Other show mines are the ''Büchenberg'', ''[[Drei Kronen & Ehrt]]'', the ''[[Röhrigschacht]]'' show mine, the ''Lange Wand'' show mine in Ilfeld and the ''Rabensteiner Stollen'' show mine in Netzkater.
Others have been turned into mining museums, like the [[Upper Harz Mining Museum]] in Clausthal-Zellerfeld, the [[Lautenthal]] Mining Museum with its pit railway or the [[Rammelsberg]] Mining Museum near Goslar, which is a [[UNESCO]] world heritage site. The [[Roter Bär Pit]] in St. Andreasberg also served as a training mine until the 20th century and is today, preserved true to the original, as a [[visitor mine]].
