Rocks of Fort Williams Park

July 16, 2019 – 6:30 pm

SPPL welcomes Professor Mark Swanson for a photographic tour through the rocks and geologic structures exposed at Fort Williams Park and the Portland Head Light in Cape Elizabeth, Maine on Tuesday, July 16th, at 6:30 p.m. at the Main Library. The rocks at this popular coastal park display a long 400 million year history of folding, stretching, shearing, fracturing, veining, dike intrusion and erosion long before being submerged beneath the ocean, buried by glacial sediment and then uplifted to where they are today.  Come for a visual field trip through the fascinating rocks and structures that you can see throughout this spectacular coastal location!

Swanson is a professor in the Geography-Anthropology Department at the University of Southern Maine with 35 years of field research into the deformation history of Maine’s coastal bedrock. He has a Ph.D. from State University of New York at Albany, a M.S. from Lehigh University, Bethlehem, Pennsylvania and a B.S. from Northeastern University, Boston, Massachusetts.
