In partnership with the Archaeological Society of Southern Florida, a non-profit, volunteer organization which acts as a support mechanism for the office of the Miami-Dade County Archaeologist, the Deering Estate presents a monthly lecture highlighting unique and interesting connections to our past. This serves as a focal point for local archaeology enthusiasts and professionals in the field, and helps to promote knowledge and appreciation of native archaeological and historical sites in the South Florida area.
The Archaeological Society of Southern Florida meets at the Deering Estate on the 2nd Thursday of the month (Seasonal: September 2015 through June 2016)
Thursday, September 8, 2016 at 7:00 pm
Topic: “Discoveries at Deering: The geologic and environmental record from caves and sinkholes on the Atlantic Coastal Ridge of southeast Florida”
Presenter: Dr. Lee Florea, associate professor of Geological Sciences at Ball State University
Dr. Lee Florea of Ball State University will share recent geologic discoveries made at the Deering Estate. This work is in cooperation with ongoing archaeological investigations and follows upon the work conducted at the Cutler Fossil Site, a sinkhole located on the Estate, which has yielded late Pleistocene mega-fauna and projectile points dating from thousands of years ago, and original exploration of several caves on the property in the early 1990s. Florea and collaborators have mapped seventeen caves since 2008.
Recent archaeological investigations from middens and other material at the Deering Estate has produced evidence of significant habitation during the Paleo-Indian, Archaic and more recent periods. However, during Florea’s studies, sediment cores obtained from sinkholes at the glade margin of the Estate have all been carbon dated to post-Spanish contact (>1485 CE).
Following sea level rise at the end of the Pleistocene era, the complex interactions of Biscayne Bay and the Everglades ecosystem created seasonal wetlands in transverse glades of the Atlantic Coastal Ridge. Data from sediment cores suggests charcoal production and mobilization of sediments into Deering Glade between 1485-1640 CE is the product of changing land use or environmental conditions.
About the presenter:
Dr. Lee Florea is an associate professor of Geological Sciences at Ball State University in Muncie, Indiana. His research includes hydrogeology, geochemistry, and geophysics, and largely focuses upon cave and karst landscapes and the aquifers that enclose those caves, such as the Biscayne aquifer. He is an alumni of the University of South Florida in Tampa and a former postdoctoral scholar with the USGS in Ft. Lauderdale.
