Age. Mid Wisconsin. A radiocarbon date 19,890 ± 120 ka for large mammals collected from the upper layers was obtained from caliche (Wake and Roeder 2009). Fish, amphibian, bird, and small mammals occurred in an older deposit (40,980 ± 800 ka) obtained from dating of a freshwater mollusk shell (Wake and Roeder 2009).
Description. "The site lies in stabilized Pleistocene dune deposits consisting primarily of fine-grained fluvial sands with isolated deposits of silts and clays" (Wake and Roeder 2009:364).
Discussion. "The species composition of the LACM 7679 microfauna and flora suggests that mesic riparian zones were more widespread in southern California during the late Pleistocene, but still closely associated with drier sclerophytic scrub and chaparral habitats more common in the region today" (Wake and Roeder 2009:369).
