South Carolina Studies: Bringing the Geologic Time Scale Down to Earth in the Students' Backyard part of Rates and Time:GSA Activity Posters
John Wagner, Clemson University
Students visit Drayton Hall historic plantation near Charleston, South Carolina and are led on a field trip that starts with a discussion of documented historic changes that have affected the mansion and the surrounding property. The field trip continues with a study of Native American artifacts and ends with analysis of coastal plain deposits exposed along the Ashley River. Students use paleogeographic maps to discuss both historic and prehistoric changes to the landscape. Back in the classroom, students gather data to draw paleogeographic maps of their own school site through geologic time.
