Small rockshelter with shell midden, prickly pear (Opuntia) abundant near mouth, stratigraphic integrity good. Twenty m south of CA-Ora-1082.
The pollen concentration is high and the preservation is good at this site, which is either young or very thoroughly mixed. The historic indicators ( Cruciferae, Erodium cf. cicutarium, Sporormiella, and Thecaphora are present to base of the sediment column. The restriction of ragweed (Ambrosia) pollen to the surface and Mirabilis pollen to the base indicates that mixing is not complete, if present at all.
Prickly pear (Opuntia) pollen is very abundant.BACK
