Who discovers the gabion?

Which rocks can be found in it(no rock extraction!)?

From the red sandstone formation, mainly slab sandstone (1) can be seen, often rich in mica. But at least one block of boulder sandstone (2) was also used, clearly recognizable by the milky quartz inclusions (3). Particularly hard granites (4), gneisses (5) and rhyolite/quartz porphyry (6) from the railroad ballast can also be seen.


Continue for approx. 30 m until the "Untere Grabenäcker" road, which is marked as a footpath, branches off to the left. Follow the footpath for approx. 60 m until it meets the road "Am Bahndamm". Turn right here onto the small footpath and follow it for approx. 100 m until it becomes a road again. Cross the crossroads with the children's playground on the left and follow the road for approx. 150 m until you reach the signpost "Haltepunkt Feldrennach". Turn left up here onto a grassy path in the direction of "Lohwäldle (SWV)" and follow this for approx. 300 m. Keep right at the next fork. Shortly afterwards, to the right of the path, hidden in the trees, you will find a strange boulder...
