ネッカーテンツリンゲンの天然記念物・トップ20

Viewing platform above Metzingen with various seating areas and a wonderful view of Metzingen and the surrounding area.

In July, the largest lake in the Schaichtal is almost overgrown with a green dress of aquatic plants.

Always along the edge of the disused quarry.

The edge of the former quarry is impressive. The path leads over the grad, with demanding vertical meters to be mastered up and down.

Impressive former quarry on the Hörnle. Thanks to a citizens' initiative in the 1960s, the Hörnle was not completely removed. Because that could have happened from the Dettinger side. So we have a unique natural paradise on the Albtrauf between Dettingen, Hülben and Neuffen.

Walter Röhm, author of the Bad Urach hiking book, explains how the hell holes came about so - actually they are cracks in the rocks of the Weißjura delta lying on top in this area of the Alb - so that the underlying marl layers of the Weißjura gamma are to be regarded as impermeable to water. As a result, water that has penetrated into the upper layers, hitting the marl, must come out and flow down the slope and cannot seep away. During this process, according to Röhm, the layers of marl soften and become slippery, so that they no longer offer proper support to the rocks above. This process continues until individual clods tear out and go to the valley. The dizzyingly narrow rocks lying down the valley – if not already hanging – are floes that are doomed to fall but have not yet gone down into the valley, and which have already become detached from the Alb body as a result of the process described above. It will be difficult to predict when they will follow other crash candidates that have preceded them.

Very nice path through the forest.

Vertical wall at the quarry where half the mountain is missing. But very well secured.
