Hochgebirge
A Mittelgebirge (German term: 'Mittel' - middle/medium, 'Gebirge' - mountain range) is a relatively low mountain range or highland area, a typical geographical feature of central Europe, especially central and southern Germany; it refers to something between rolling low hill country or "Hügelland" and a proper mountain range ( or "Hochgebirge") like the High Alps.
