Gründelsloch Karst Spring

The Gründelsloch near Kindelbrück is one of the most impressive and important karst springs in Thuringia. It was created by the dissolution of limestone in the subsoil. The resulting underground cavity collapsed in 1611, causing a sinkhole and the spring to emerge. The active karst spring, with a diameter of 22 m and a discharge of around 15,600 l per minute, has several older precursor springs that are lined up like a string of pearls from northwest to southeast in the area of the Kindelbrück fault zone and dried up again over time. Examples of these dried-up precursor springs are the Kuhborn, around 700 meters away, or the karst spring on the Steinrinne.
