PROMENADES - DIAPORAMA Forêt de Montmorency #1 : plateau, fonds humides et le Château De La Chasse

The Montmorency forest (approximately 5km x 3km + annexes in the countryside at the ends) is very hilly and crossed by streams: varied landscapes and numerous viewpoints. You can also simply go for a picnic at the Godard pond (parking 900m away) or at the Château de la Chasse in a meadow on the edge of the ponds (parking between 500m and 800m away). Here is a 3D Google Earth flyover of all the routes I explored in the forest and surrounding countryside as well as a South East part that I have not yet visited. This video is more focused on the northern and eastern part of the D192 with journeys on the plateau then in the valley with the Château de la Chasse (other videos to come in addition). I put thicker routes for my favorite routes. In this video there are mainly, and more or less parallels: On the plateau to the north, the yellow loop: . a dirt road (the “damn road” seen in a future video): 3.6km . an old bitumen road (the summit road): 3.2km . a portion after the D192: 600m to 3.4km a portion of the valley with the road of the bottoms via the Sainte Radegonde fountain which is also a part of the orange loop route between the Château de la Chasse and the Godard pond (more detailed in a future video): + 2km The loops of the white route (more countryside: 12km) and orange route (forest, valley, middle and south: 12km) will be covered in future videos with also the picturesque pink "electric" route (2 to 3km). Various transverse connections between the loops shorten or extend the paths (in thick lines: my favorites, the best: in green) The Château de la Chasse is a 13th century fortified castle which was almost destroyed but has been restored on the outside (property of the ONF, cannot be visited). The towers were remodeled in 1728 with this sloping roof. I added some comments in subtitles (French and English) A link to a KMZ file is given at the end in the subtitles. -------------------------- Geology to summarize: . 6m of silt and topsoil (millstone, clay, marl, sand, etc.) . 60m of sand and sandstone from Fontainebleau and a small sheet of water . Then a sealed area of ​​around twenty meters of limestone and marl . Followed by gypsum for approximately 30m (20m usable) . We then find limestones, sands and sandstones . Then the water table at 133m -------------------------- Many forest cuts are linked to ink disease which mainly decimates the chestnut trees which make up 90% of this forest. They are replaced by other, more resistant species. This forest has already experienced this type of problem but, in recent years, the rains, the soil not too permeable and the droughts have aggravated the phenomenon. Note that chestnut trees were planted massively in the 18th century (vine supports, barrels, construction, heating, etc.). There are also traces of Neolithic occupation and also hosted part of the entrenched camps of Paris (1914). -------------------------- The exploitation of gypsum (plaster, cement works, fertilizers, chemicals, etc.) dates from the 19th century and is still currently carried out at a depth of 80m with 200km of galleries of approximately 10m in diameter. This guarantees the independence of France (16% of production) on this resource. Unexploited areas are filled with rubble from Greater Paris (around a hundred trucks per day). You will be able to see some ventilation chimneys in the forest. In the old disused areas of the quarries, reinforced with concrete, various command centers were set up to ensure French nuclear deterrence (base 921 in Taverny). ------------------------- Liens : https://fr.wikipedia.org/wiki/For%C3%... https://fr.wikipedia.org/wiki/Ch%C3%A... https://fr.wikipedia.org/wiki/Maladie... https://en.wikipedia.org/wiki/Oomycete https://en.wikipedia.org/wiki/Phytoph... https://bit.ly/onf_encre_montmorency https://www.placo.fr/carriere-de-gyps... https://en.wikipedia.org/wiki/Taverny... https://archives.valdoise.fr/n/le-cam... ** you can translate a web page with https://translate.google.fr/?hl=fr ** -------------------------- Music : Title : Brightness Author : Soulstorming |   / soulstorming   Music promoted by https://www.free-stock-music.com Creative Commons / Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) https://creativecommons.org/licenses/...
