バートノイエナール-アールヴァイラーの湖・トップ20

Four old ponds lie along the path as if strung on a pearl necklace. It's quiet here and perfect for a little rest.

The Dungkopfseen are worth seeing from above and below. Spectacular and idyllic.

The Dungkopf or Unkelbacher See is a former basalt quarry, which is also clearly visible on its banks. The small islet gives the whole thing something very idyllic. Unfortunately, the banks are often very dirty from any legacies.

Nice view from above through the woods

A beautiful place to rest and watch the wildlife. This time we were able to observe two pairs of great crested grebes. Simply a place for the soul.

A beautiful biotope and a wonderful place for a break.

Even experts are puzzled about the geological formation of the Rodder Maare. It is certainly not of volcanic origin, so it is not a maar. Because of its circular shape, it could have been formed by a meteorite impact. What is certain is that the Rodder Maar has experienced an interplay of irrigation and drainage, agricultural and forestry use in the course of its history. For a long time it served as a fish pond for the Lordship of Olbrück. During times of need in the 19th century it was drained to grow crops. However, the constantly damp clay soil was neither suitable for arable farming nor for fodder production. Most recently, in the early 1960s, water-draining spruces were planted and the maar was drained. These efforts had not paid off. Source: http://www.ostiefel-aktiv.de/40848/41919.html

The Königssee is 1 ha in size and 30 meters deep. Here tertiary basalt rock was mined until 1942, which was broken into gravel. The Königssee, filled with groundwater, developed from the mining pit. The basalt rock was brought to crushing plants in Oberzissen via a cable car. The gravel was brought from the Brohltalbahn to the Rhine port for shipment.
