The "Crystal Mountain" in Egypt

The Crystal Mountain is between the oasis Bahariya and Farafra, northern of the White Desert, Egypt. The Crystals are probably Barite (Schwerspat, BaSO4) and/or Calcite crystals (CaCO3). The origin of this Crystal Mountain is interesting. The hill was opened during works at the road from Farafra to Bahariya by chance and destroyed in part. The material was installed into the road. Today is the Crystal Mountain a popular stop for the tourists.
