Millions of years ago fractures in the earth's crust started to shape the landscape in this area in the east of North-Brabant. The movement between two tectonic plates sculpted a higher and a lower part of the land. Contrary to most landscapes, at this site the lower (western) area is dry and sandy, and the higher (eastern) area is wet. This is because the underground border between the two plates is so dense that the groundwater on the eastern side is pushed up. This phenomenon shapes a landscape characterised by a distinct biodiversity, and red/orange - mineral-rich - water.
