(also Mittelland), a plateau in Switzerland, between the Alps and the Jura. The Swiss Plateau extends 240 km, from Lake Geneva to Bodensee (Lake Constance), and is approximately 50 km wide. Elevations decrease from 1,000–1,200 m (maximum elevation, 1,408 m at Mount Napf) in the southeast to 400–500 m in the northwest. The plateau has a hilly relief with numerous lakes. On the Swiss Plateau are fields, orchards, and tracts of oak, ash, and beech forest.
