The Schulerloch is of palaeontological interest. It was the shelter for Neanderthal man during the middle paleolithic. The humans used only the front part of the cave, but in the rear part the remains of numerous animals of the Würm Ice Age.
In early bronze age, the cave was inhabited by humans again. But then the entrance was walled up, the reason is unknown. The cave was forgotten until the middle ages, when it was rediscovered.
The man who developed the cave, Anton von Schmauß, was freemason. He placed the inscriptions above the entrance, and a statue of Goddess Isis, the Goddess of Nature. He also built a pavilion above the entrance, suitable for living, and a second one nearby, which hosts a museum today. This small museum shows some exhibits about the cave, the Altmühl valley and the Rhein-Main-Donau-Kanal (Rhine-Danube-Canal).
The Schulerloch is called dripstone cave in German. But this name is not very exact, as the speleothems in this cave are composed of moonmilk. Moonmilk is a white, opaque speleothem consisting mainly of calcite, but may also contain hydrocalcite, hydromagnesite or huntite. It covers big areas on walls and ceiling. But regular dripstone, stalagmites and stalagtite composed of calcite crystals, are very rare in this cave. An exception are two beautiful rimstone pools at the end of the cave. But this lack of common speleothems gives the cave a special character.
The cave is formed in corall reef limestones of the Jurassic. This limestone has no layers and so the chambers are of irregular shape. The complex structure of the arched ceiling give the cave a special acoustics. An extraordinary Didgeridoo during my cave tour was a real impressive experience.
The cave is said to be 1.5 Million years old. At this time the Altmühl-Donau was 55 m higher than today and was the drainage of the cave. The Altmühl-Danube was a combination of todays rivers, as the danube used this part of the Altmühl valley at this time. The cave was formed during a period of stagnancy in the cutting in of the river. The the river restarted to cut in, the Danube changed its bed and the Altmühl continued to cut until 200,000 years BP. The Danube formed the famous canyon of Weltenburg, which is nearby. The connection between Danube and Altmühl is today called Dry Valley of Wellheim.
The Schulerloch is often called Großes Schulerloch (Big Schulerloch), because there is also a small Schulerloch, the Kleines Schulerloch. This small cave is not open to the public, and contains an engraving showing a hind or an ibex. It was discovered in 1937 by the two local historians A. Oberneder and O. Rieger.
The engraving has a certain similarity to paleolithic engravings in French and Spanish caves. Prof. Birkner, Dr. Wagner and Prof. Obermaier called it the first ice age engraving in Germany. But Prof. Zotz from Erlangen was much more sceptic, and because of the minimal weathering he thought it was a fake.
The actual state of scientific research dates the engraving to the late Magdalenian, 10,000 BC. But this is not proofed by geophysical methods, its just based on an analysis of stile and technique. A proof of its age is at the moment not possible.
Below the engraving several runes from the 6th to 8th century can be found. Their closeness to the stone age engraving made their interpretation even more difficult. The runes form three words: BIRG LEUB SELBRADE. Birg is a female first name, the ancestor of Birgit or Brigitte. Selbrade is a male first name. Leub means love, vow, dedicate. The interpretation is rather easy... A replica of the engraving is on display in the small museum near the cave entrance, mentioned above.
