Rolled and abraded flint artifacts were discovered in 1928 in the cave of Shukbah in the Judean mountains. The phenomenon was later noted in three additional caves – El-Wad, Skhul and Raqefet, all in Mount Carmel. Three abrasion events are identified. Admitting the indispensable role of water in the abrasion phenomenon, rain, river and sea were suggested in the course of time as possible agents. This study supports Garrod's, D.A.E. [1928. Excavation of a Palaeolithic Cave in western Judaea. Palestine Exploration Fund Quarterly Statement 60, 182–185] original suggestion of abrasion by rain water. Stratigraphical considerations matched by speleothem-based rain history in the southern Levant suggest that these events occurred ca. 150 ka, 80 or 55–50 ka, and 35–32 ka BP.
