|The Hannoverschen Klippen, a part of the Weser mountain country (Weserbergland), are in the southwest of the low mountain range Solling directly on the northern bank of the river Weser. They rise between the villages Bad Karlshafen (Hessen) and Würgassen (North Rhine-Westphalia) and are the only natural rocks of the Solling. The easternmost of the seven cliffs carries a prospect platform, from which one you have a wonderful view over the Weser mountain country.
The emergence of the Hannoverschen Klippen hands back approximately 250 million years. In the age of the early earth Middle Ages (Trias) river systems from the south rinsed loose sand near, which settled in the area of the today's Weser mountain country. In the course of the millions of years the deposited layers reached a strength of more than 1000 meters.
Under this load the loose river sands solidified itself to sandstone. Later it came to a flat, shieldlike upbulging of the deposited rock formations. In the future by erosion the upper surface layers consisting of shelly limestone were cleared away. The Weser, incisioned between Solling and Reinhardswald uncovered here the to the west subsidenced layers of the bright sandstone in a sequence of cliffs. During last one million years the Weser cut itself 20 centimetres per millenium into the valley.
Above the cliffs still today the Weser sandstone, also Buntsandstein mentioned is diminished, which finds cut in plates for roofing or horticulture.
Log conditions: Answer the following questions and send us the answers:
1. Which colour has the sandstone, which is broken in the quarry in the proximity of the cliffs?
2. How are the earth Middle Ages, to which the Trias belongs, called scientifically?
3. How many meters do the cliffs arise above the river Weser?
It would be nice, if you could submit a photo with your log.
The answer to question 2 will not be found locally!
