Chaltbrunnental Grellingen Meltingen Switzerland Gorge

Höhlen im Chaltbrunnental Grellingen Meltingen Switzerland Gorge: https://s.geo.admin.ch/tgih6pcnscyv The Kaltbrunnental (Swiss German: Chaltbrunnetal) stretches from Meltingen along the Ibach River, with steep rock faces reaching up to 60 meters in height, all the way to where the Ibach flows into the Birs at Chessiloch. Within a small area, the Kaltbrunnental features a variety of karst landscape formations, such as disappearing streams (sinkholes), springs, and caves with associated tunnel systems. Caves with prehistoric sites Heidenküche The Heidenküche is located a 10-minute walk from Chessiloch into the valley on the right bank of the Ibach, 13 m above the stream bed in the municipality of Himmelried SO. Excavated in 1883 by J.B. Thiessing, the cave is one of the first Paleolithic sites discovered in Switzerland, alongside the Kesslerloch and the cave near Liesberg. Evidence of human occupation during the late Magdalenian period has been found. Kohler Cave Kohler Cave was named after Heinz Kohler, a young man from Grellingen, who was able to squeeze through the approximately 40-centimeter-high opening in late fall 1934. Subsequently, it was systematically explored by Kohler, Karl Lüdin from Basel, and Emil Kräuliger (1879–1950), a teacher from Grellingen. The cave is located across from the Heidenküche, on the left bank of the Ibach, 6 m above the stream bed in the municipality of Brislach, Basel-Landschaft. It was discovered in 1934 by Heinz Kohler of Grellingen. In the lower stratum, evidence of prehistoric visits by Neanderthals more than 30,000 years ago was found, and in the upper stratum, evidence of visits during the late Magdalenian period. Kastel Cave The Kastel Cave is a 10-minute walk from the Kohler Cave, heading upstream on the right side of the valley, 30 m above the stream bed in the municipality of Himmelried (Schindelboden). It was discovered in 1948 by Walter Keller of Allschwil. In the lower stratum, evidence of prehistoric human activity by Neanderthals more than 30,000 years ago was found; in the middle stratum, the first evidence of anatomically modern humans (Homo sapiens) in Switzerland from the Early Magdalenian period was discovered; and in the upper stratum, evidence of human activity during the Late Magdalenian period was found. Kaltbrunnental-Brislachallmet Karst Nature Trail The 9.5-kilometer-long Karst Nature Trail leads from Zwingen toward Schälloch, through the Brislachallmet into the Kaltbrunnental valley, and from Chessiloch to Grellingen. It is marked with white signposts and features informational panels explaining the diversity of the karst landscape, prehistoric cave finds, and speleology. It was initiated by the local speleological society and is maintained by the Kaltbrunnental-Brislachallmet Karst Nature Trail Association. In addition to the caves in the Kaltbrunnental, which have long been known as sites of prehistoric settlement, the trail passes by the Bättlerloch, the longest cave in northwestern Switzerland.
