Mountain Biking Highlight
The "Stein" is an approximately 547 meter high Molasseberg southeast of the village of Weiach. On top of the sandstone and marl of the Molasse lies a layer of the so-called “middle-layer gravel”. The former river pebbles are partially cemented together. This means that they resist erosion better than the lower-lying molasse layers and therefore form striking rock faces on the north side against the Rhine and on the south-west side. This contrasts with the plateau-like plateau on top of the "stone".
Rock wall formed by middle ceiling gravel on the south-western edge of the "Stein"; steam rises in the background from the cooling tower of the Leibstadt NPP.
On the plateau-like plateau on top of the "stone".
The best view is from the plateau edge of the "Stein" in winter when the deciduous trees are bare. In places the view recurs to the Alps.
At the foot of the rock wall formed by the middle gravel, a small cave has formed due to weathering.
The middle gravel was deposited in an earlier ice age, not the last one, and is therefore at least 200,000 years old. If the molasses below them are removed by erosion, the ceiling gravel can temporarily form unstable overhangs. Finally, rock masses break off and descend as small rock falls over the mountain flanks. The descended gravel blocks form enchanting small landscapes in some places in the wooded slopes.
