Easy hikes and walks in Kalltal Und Nebentaeler

In view of the (in the worst sense of the word 'brand'-)current headlines about the devastating fire in the North Eifel (Hürtgenwald) and the nearby (Belgian) "Hohes Venn", the scale of which has so far reached unimaginable dimensions in the cross-border region, I recommend to nature-interested viewers a film documentary in the ZDF media library: An episode from the series »plan b« – titled "Forest protection in the climate crisis" – illuminates the background to the condition of our native forests and asks urgent questions. The contribution is available online at =>> https://www.zdf.de/play/dokus/plan-b-104/plan-b-waldschutz-in-der-klimakrise-100?staffel=2023

Given the (in the worst sense of the word 'brand') current headlines about the devastating fire in Hürtgenwald (DE) on the one hand, and the neighboring High Fens (BE) on the other, whose extent has so far reached unimaginable dimensions in Germany and Belgium, I recommend a film documentary in the ARD media library. It sheds light on the background and asks the exciting question: 'What comes after the forest fire?'

The bunker is marked in the wrong position, this is Bunker No. 59.

The pilgrim's cross, erected in 2008 in a modern stainless steel design, draws attention to the annual Ascension Day procession from Düren-Lendersdorf to Bastogne, Belgium (approximately 115 kilometers away). This tradition has taken place since 1720 and celebrated its 300th anniversary in 2020.

The Hohes Venn-Eifel Nature Park contains several reservoirs and dams that regulate the rivers and streams in the Eifel region. These reservoirs, such as the Rurtalsperre Schwammenauel, Urfttalsperre, and other smaller dams, were constructed to control water levels, supply drinking water, prevent flooding, and in some cases, generate electricity from the water flow. Water release valves (also called sluice gates or valves) are technical components in dams and reservoirs that allow operators to control the release or flush of water, thus regulating the water level in the reservoir. Without these valves, water would only flow downward via overflows and natural outflows, which can lead to dangerous water levels in the event of excessive rainfall. In large dams like the Rurtalsperre Schwammenauel, these valves are part of a complex system of pipes and control houses. At the bottom of the dam, large steel pipes typically contain multiple valves (e.g., butterfly valves or special release valves) that allow large volumes of water to be released from the reservoir in a controlled manner. These valves can be mechanically or electrically operated and are a vital link in the lake's management. The valves themselves are robust, large mechanical structures specifically designed to withstand high water pressure and tens of thousands of cubic meters of water. Large dams incorporate multiple valves to enable various water management scenarios, from slow release during light rain to rapid release during extreme weather. Dams like the Rur Dam (Schwammenauel), for example, use butterfly valves and special release valves in the dam's bottom outlets. These components allow for the controlled release of water from the reservoir's depths, while also serving to discharge sediment and limit erosion in the downstream channel. In the Hohes Venn-Eifel Nature Park, these water management systems are embedded in a landscape where nature, recreation, and water management converge. The reservoirs and their release valves not only help protect the region from flood risk but also support the ecological balance of river valleys and provide peaceful recreational areas for hikers and cyclists.
