New Environmental Proxy Data from Little Salt Spring, FL
Little Salt Spring (LSS) is a ~70m deep sinkhole located in south-west Florida. Paleo-Indian and Archaic Indian artifacts suggest two periods of occupation: from 12,000 ‘ 9,000 and from 7,000 ‘ 5,000. In order to provide climatic context for the archaeological finds at LSS sediment cores (n = 5) were taken in 1990 using a submersible vibro-corer. Previous examination of these cores for pollen and microfossil data were used to infer drier Early Holocene climate followed by a shift to more modern, wet conditions and higher water table ~ 5000 years ago coinciding with the abandonment of this site. To gain further understanding of climate and its relation to human migration patterns in Florida, an 8.2 m sediment core dated between 13,000 and 6,000 yr BP was further analyzed for additional proxy data. Grain size and carbon/nitrogen ratios will be used to determine regional sediment inputs while microfossil analysis will give insight into changing hydrology of the sinkhole and how it may have affected early occupation.
