Großer Heuberg or Grosser Heuberg, often simply called Heuberg, is the name of a sparsely populated plateau in the southwestern Swabian Jura with mountains of about 1,000 metres above sea level or even higher. The word beginning Heu is German for hay, which was the major income source for the inhabitants in recent times and is until today formative for the landscape of the Heuberg. The word ending berg means mountain.
