Pollen grains and gastropod shells in two speleothems from Red Spider Cave, Georgia indicate that ca. 10,000 yr B.P. the vegetation near the cave was Mixed Mesophytic Forest. Conditions were cooler and moister than today and a shallow pond existed in the doline above the cave. As these findings support palynologic evidence from nearby pond sites it is clear that cave speleothems are a potential source of paleoecological data to ca. 350,000 yr. B.P.
