Summary

[edit]
Description
Deutsch: Das Gipfelplateau des Aachener Friedrichwaldes, eines Zeugenbergs im Sinne der Geologie, besteht aus plateaubildenden Kalkschichten. Darunter befinden sich in großer Mächtigkeit die leicht erodierbaren Vaalser Grünsande.

Wie diese Kombination zu dolinenartigen Einbrüchen führen kann hat der Aachener Professor der Geologie, Roland Walter (emeritierte 1999) ausführlich anhand einer nahegelegenen ähnlichen Lokation am Nordhang des Vaalserbergs beschrieben [1]. Verschiedene Prozesse, unter anderem in Verbindung mit Sickerwässer, spülen die Sande unten aus, entfernen zum Beispiel die feineren Bestandteile. Die Sand sacken zusammen und von oben stürzen die Kalkschichten nach unten nach.

Die rote Pflanze im Bildvordergrund ist sehr wahrscheinlich eine Pestwurz. Bei der Pestwurz kommen erst die Blüten mit den Früchten und dann erst die Blätter.
