The Late Quaternary history of northern Sinai and the western Negev is inferred from a number of stratigraphic sequences rich in prehistoric and archaeologic remains. Exposures are abundant along the wadi courses which drain the highlands westward to the Mediterranean. Earliest deposition is represented by coarse, well rounded gravels containing Middle Paleolithic artifacts and is dated to ca. 90,000 to 70,000 B.P. These are overlain by finer grained sands, silts, and clays, ultimately of eolian origin, but re‐deposited by low energy stream flows under marshy conditions. These contain in situ Upper Paleolithic (ca. 40,000 to 22,000 B.P.) and Epi‐Paleolithic (ca. 15,000 to 12,000 B.P.) sites; commonly an erosional phase (ca. 22,000 to 15,000 years ago) separates the two groups of industries. In areas closer to the coast, temporally equivalent deposits are predominantly sandy, reflecting their proximity to the source in western and northern Sinai. The Holocene is generally characterized by downcutting but deposition of fluviatile and eolian silts is well documented during the Chalcolithic (ca. 6,000 B.P.). The last depositional event is the accumulation of 3–4 m of fluviatile silts containing Byzantine artifacts and radiocarbon dated between ca. 1750–600 B.P.). Whereas most of the sequences can be explained in climatic terms, the Byzantine or “Historical Fill” may have an anthropogenic origin.
