“…To evaluate the possible disturbances generated by katabatic winds on the Lower and Middle Palaeolithic populations, the orientations of the 82 sites previously described by Monnier (1982) were re-analysed. Following recent studies (Huet, 2002(Huet, , 2006Monnier et al, 2011;Bahain et al, 2012;Laforge, 2012;Laforge and Huet, 2013;Danukalova et al, 2017;Laforge, 2012;Lefort et al, 2019a,b) it was possible, even after 40 years of erosion by the sea, to check the orientation of most of these sites. Because of this comparison, we noted that apart from the small cavities in rock collapses, crevices or overhangs in loess or granite cliffs (representing 40% of the sites) and the sites very close to a cliff (38%) with clear orientations, most of the other directions (22%) of Monnier (1982) matched the direction of the maximum topographic dip at or near the archaeological site.…”
