Like the pages of a book, each sequence has preserved the trace of climate phenomenon and human occupation. As visitors makes their way along, starting from the oldest layers located at the base of the stairwell (a cross-section from the Vaufrey cave) all the way to the most recent located at the top (a cross-section from Laugerie-Basse), they see that a nearly continuous record of time is present in Perigord, a sequence in which the impact of human activities is more and more visible (a richness of tool relics, ashes, coal…).
