| | Swabian Alb, Germany |
 | | The Swabian Alb, an upland region of Jurassic limestone of about 700m/2,300ft in height, extends for 210km/130mi, varying in width between 15km/9mi and 40km/25mi, from the southeastern edge of the Black Forest, where it reaches a height of 1015m/3,330ft in the Lemberg, to the Ries depression around Nördlingen. |
 | | In the northwest the hills drop down to the valleys of the Neckar, the Fils and the Rems in a steep scarp some 400m/1,300ft high, which is broken up by valleys reaching deeply into the hills (several ruined castles are perched on outlying crags). |
 | | To the southeast, the Alb slopes gently down to the Danube in a gently undulating plateau of permeable limestone, through which most surface water seeps away, forming caverns, swallowholes and dry valleys. |
