Landforms of Lot (department)

The Causses () are a group of limestone plateaux (700–1,200 m) in the Massif Central. They are bordered to the north-west by the Limousin and the Périgord uplands, and to the east by the Aubrac and the Cévennes. Large river gorges cut through the plateaux, such as the Tarn, Dourbie, Jonte, Lot, Vis, and Aveyron. Causse is an Occitan word meaning "limestone plateau" coming from the latin word calx meaning limestone or chalk.
