Harz or Hartz Mountains: In German Harzgebirge, were called in the Eighth Century Hart (Old Saxon hard, Old High German hart, "wood" or "forest"). The present spelling, Harz, is supposed to be due to a folk etymology which has made the name into Harzwald, the "forest of resin" (harz). The Hardt, a wooded range of hills near Carlsruhe, is the "wood."
