Geology of Pine Mountain and Warm Springs
Join geologist, Dr. Bill Witherspoon, co-author of Roadside Geology of Georgia, for a rockin' indoor and outdoor presentation, “The Ridge That Drew Roosevelt,” and visit FDR’s favorite overlook. Roadside Geology of Georgia “takes the general reader to Georgia’s natural wonders and explains the science that lies behind the scenery,” according to Witherspoon. The program will begin at 1:00 PM in the Enclosed Group Shelter below the dam at the park’s campground. With a slide show and animations, Witherspoon will explain Pine Mountain and Warm Springs in the context of billion-year-old rocks and shifting continents, and discuss evidence for and against an asteroid impact centered on The Cove near Woodbury. Attendees then will carpool to Roosevelt’s favorite picnic spot and overlook, Dowdell’s Knob. They will examine the Hollis Quartzite, a rock formation that began many years ago as a sand deposit along a shoreline. Now the resistant rock that supports Pine Mountain, it also has fractures that guide rainwater from the mountaintop to deep below the surface, to bubble up again as Warm Springs. The Knob also affords a view across landscape developed on old rocks to Oak Mountain, similarly a ridge in Hollis Quartzite. The program will conclude by 3:00. Pre-register at the Park Office or $4 correct change at the door. Event will be held at the Group Shelter below the campground dam and then carpool to Dowdell's Knob. $5 parking pass is needed.
