Free lecture at the Deering Estate

MIAMI (August 10, 2016)

In partnership with the Archaeological Society of Southern Florida, the Deering Estate presents a free lecture on the 2nd Thursday of each month at 7:00 pm. Lectures are held in the Visitor Center Theatre at the Deering Estate located at 16701 SW 72 Avenue. The lecture on Thursday, September 8, 2016 is "Discoveries at Deering: The geologic and environmental record from caves and sinkholes on the Atlantic Coastal Ridge of southeast Florida."

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, Ball State University
Deering Estate, Visitor Center Theatre; FREE & open to the public.

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.

About the Archaeological Society of Southern Florida
The Archaeological Society of Southern Florida (ASSF) was established in 1949. The ASSF operates as a non-profit, volunteer organization which acts as a support mechanism for the office of the Miami-Dade County Archaeologist, 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.

About the Deering Estate
The 450+ acre Deering Estate is an environmental, archaeological and historical preserve. From canoe tours to butterfly walks and guided nature hikes, the Deering Estate has diverse activities for the whole family to enjoy. The Estate is part of the Miami-Dade County Parks, Recreation and Open Space Department, which manages the Estate on behalf of the State of Florida.

The Deering Estate celebrates 30 years of being on the National Register of Historic Places. #DiscoverMore history, art, culture, science, preservation, conservation and ecology at the Deering Estate!
