In the southeastern part of the Leine Uplands, east of the valley, is the plateau of the Göttingen-Northeim Forest which is founded on Bunter sandstone and Muschelkalk.
The western edge of the forest (in a northerly direction) reaches from Friedland via Göttingen and Nörten-Hardenberg to Northeim.
West of the trough is the heath landscape of the latter opposite the intensively farmed Solling Foreland.
After the Leine trough has been blocked and flows around the Hube, it runs through the Alfeld Uplands (Alfelder Bergland), also called the Ith-Hils Upland (Ith-Hils-Bergland), which is characterised by a succession of closely spaced ridges and finger valleys running in a northwest-southeast direction.
East of the massifs that give the region its alternative name, the Ith and the Hils, which are up to 480 m high, the ridges fall steeply on both sides of the Leine into the valley and are dissected by various tributaries.
