Charles E. Stearns was a geologist at Tufts University who collaborated with the American School of Prehistoric Research in North Africa during the late 1940s. He participated in the 1949 excavations at Tipasa and Kouali Point, Algeria, where his geological expertise was critical in correlating archaeological horizons with sea-level fluctuations and coastal geomorphology. Stearns’s mapping and stratigraphic studies allowed the ASPR team to situate Paleolithic and Neolithic industries within a broader environmental framework. His work took an interdisciplinary approach, demonstrating the importance of geology in reconstructing the prehistoric landscapes.
