    On the right side of the quarry you can see the grinding and flow marks very well.

    Hiking

    Greywacke is the typical rock of the Harz Mountains. It is a gray to green-gray sedimentary rock with a high proportion of rock debris. The name is an old Harz mining term, used since at least 1784 as "grey wacke of the Harz," and simply means "gray rock."

    Greywacke was mined here in the quarry. Greywacke is very frost-resistant and was therefore used, among other things, for the ditches and dams of the Upper Harz water management system.
