Westhessische Senke
The West Hesse Depression runs along the valleys of the Schwalm, Eder, Fulda, Esse and Diemel roughly from Alsfeld in the south to Bad Karlshafen in the north. It separates the East Hesse Highlands (major regional group 34 or D46), including the Knüll hills and Kaufungen Forest in the east, from the West Hesse Highlands (35 or D47), including the Kellerwald and Habichtswald in the west and is itself part of the West Hesse Highlands, within which it is included as geographical unit 343.
