The culture was geographically widespread, and later Magdalenian sites stretched from Portugal in the west to Poland in the east, and as far north as France, the Channel Islands, England, and Wales. It is the third epoch of Gabriel de Mortillet's cave chronology system, corresponding roughly to the Late Pleistocene. Besides La Madeleine, the chief stations of the epoch are Les Eyzies, Laugerie-Basse, and Gorges d'Enfer in the Dordogne; Grotte du Placard in Charente and others in south-west France.
