Mattia Pastore
May 7, 2025, Findlinge aus der Steinzeit - Grosse Fluh mit erratischer Block

This boulder is called Grossi Flue. It weighs a whopping 3,500 tons and has a volume of 1,200 cubic meters. The boulder was brought here by the Rhone Glacier – this is evident from the hornblende gneiss. The enormous boulder was purchased by the Swiss Society of Natural Sciences in 1869 and placed under protection. Otherwise, it would likely have fallen victim to railway construction.

From the viewing platform on the Roggenfluh, the view of the Mittelland and the Alps is simply brilliant, the two large panoramic maps explain all the mountains from the Glaner Alps to Mont Blanc.

The Roggenflue is a wonderful panoramic mountain in the Solothurn Jura and the hike from Balsthal is really beautiful.

The Burgäschisee, sometimes also simply Aeschisee, lies on the canton border of the cantons of Bern and Solothurn, with around two thirds on the Solothurn canton area. The lake is located in the municipalities of Aeschi (SO) and Seeberg (BE) at an altitude of 465 meters above sea level. The lake is fed by the Füürstein Canal, while the Seebach flows out. The natural lake is almost 700m long and 500m wide and is surrounded by a forest and reeds. The lake is located in a nature reserve.

Probably the most unmistakable signs of the beaver's return are neatly gnawed tree trunks on water. Due to its semi-aquatic way of life, it needs trees, especially softwoods such as willows and alders, which it turns down to get to the branches. He then gnaws these off to build dams to design his building and from the bark he gets his winter fodder. By felling trees and damming the water, the beaver has a great design effect on the landscape. By creating dams, the beaver has fundamentally intervened in the structure of the stream. A new dynamic is developing in the monotonous flowing water. A multitude of different habitats are created; deep water points directly at the dam, shallow and slow-flowing sections enriched with mud above, fast-flowing water below the dam. Due to the high water level in places, the water gets rid of its sludge in the vegetation, making it clearer. The gnawed dead wood is deposited in places and forms protection for the fish fry, but also nesting places for birds. The alternation of gnawed trees and sprouting wood rejuvenates the bank vegetation and leads to a mosaic of different living conditions.
