Trilobite to Staurolite: A Geo-delicious Slice Through Northwest Georgia with Dr. Bill WitherspoonRoadside Geology of Georgia co-author Dr. Bill Witherspoon takes you on a journey through time and space, from Georgia’s northwest corner to Greater Atlanta. Why do the rocks in the first location preserve delicate impressions that extinct critters left in mud, while at the second location, rocks are “well-cooked” enough to have erased fossils and grown crystals such as staurolite “fairy crosses”? Why are layers of mud at the first location as smooth as the day they settled out of water, and at the second contorted beyond recognition, even melted? And how did the discovery 60 years ago that continents are in motion cast the answers to these questions in a whole new light?
See nature at scales from microscopic to continental, expand your understanding of the contrasts between the Valley and Ridge and the Piedmont regions of Georgia, and glimpse the breadth of knowledge that scientists have gained about our planet.
Arrive early at 6:30PM and join Bill for a look at the Piedmont geology revealed on the hill above our meeting place at the Nature Center.
Attend in-person at 7PM in the Discovery Center Cowie Weiss Theater and bring a dish to share for the potluck. Make new friends and connections at Nature Club while learning all at the same time. The presentation will begin at 7:30PM.
