Cave finds in the so-called Käsloch near Winznau (Canton of Solothurn).
I. Find report. By Ed. Bally Jr.
During a lecture on the prehistory of the Solothurn Niederamt, given by District Teacher Furrer in Winznau, the speaker was informed by the locomotive driver, Mr. von Feiten, that near the von Felten house there was a cave in which worked flint and bone fragments had been found several times. An on-site inspection revealed that this was a prehistoric dwelling. The systematic exploitation of the cave was undertaken by the speaker, as Mr. Furrer was busy preparing the find report on the Hallstatt burial mounds in Obergösgen. The investigation took place in the fall of 1905 with the assistance of Dr. Heierli from Zurich and Mr. Furrer. Fr. Schwerz, Prof. Dr. Hescheler, and Prof. Dr. Keller in Zurich were kind enough to undertake the identification of the human and animal remains, while Mr. W. Frey, a technician in Schönenwerd, took care of the plan survey.
The cave is located at the western exit of the village of Winznau, to the right of the main road to Ölten, approximately 400 meters from the new bridge, at a height of approximately 40 meters above the Aare River. Sloping steeply to the west-southwest (32°), the terrain is partly covered by deciduous forest, and in parts the almost vertical cliffs are directly exposed. From the cave itself, there is a wide view of the Aare Valley. Thus, the cave offered people a strongly fortified habitation, in the immediate vicinity of which a powerful spring bubbled from the rock. Known as "Käsloch," it has served as a playground for village youth and a camp for wandering people to this day.
