Impact of katabatic winds on the environment of Neanderthals during the Middle Palaeolithic in westernmost Europe
ABSTRACT Compilation of the offshore and onshore altitudinal limits of the loess deposits of western France and southern England shows that they were deposited by low‐level wind fields. These relate to (i) the deflation of silt‐rich sediment extracted from the outwash plains of the not far distant B...
