About 250,000 years ago, the Rodderberg volcano reawakened. A particularly well-visible testimony to the slag eruptions is a fissure filled with lava that penetrated the slag deposits in the northern quarry. The slag was mined, and the basalt dyke remained standing due to its greater hardness. It can still be admired at this spot today. https://www.geocaching.com/geocache/GC1TKGT_rodderberg-vulkan

The pollarded beeches in the Kottenforst Bonn forest near Waldau are mostly common beeches and up to 250 years old. The origin of the pollarded beeches has an earlier agricultural background. Back when wood was still used for heating, so-called forest pastures were established, i.e., meadows were planted with beeches. The beeches were then regularly pruned after 10 to 15 years to a height of approximately two meters. The beeches, which continually sprouted new shoots, grew back, and the cut-off portion was primarily used as firewood.

Very nice for a nature reserve in a city. I prefer less frequented nature reserves (e.g., the Eifel region).

This section is very muddy after the rain. There are dozens of fallen trees. Unfortunately, the bridges have some damage. According to the sign, the path is no longer maintained. What a pity!
