Carreau Rodolphe spoil tip

Head towards the exit of the car park, towards the old slag heap which is part of the Carreau Rodolphe, the site of the Potash Mines of Alsace, the first shaft of which was drilled in 1913 by the Société Kali Ste Thérèse. This site is a witness to the past glory of the mining industry and has been owned by the Conseil Général since 1987. A team, the "Rodolphe Group", has been fighting since 1994 to rehabilitate and develop the site, in order to preserve the memory and tools of the MDPA miners. We follow the cycle path, with moorland and reed beds on our right, which were created by the discharge of brine in 1960, causing the trees to die in these marshes.
