She is speaking on  "Terra Firma? Living on the Edge in Southeastern Pennsylvania."  We will learn the fascinating geologic history of southeastern Pennsylvania.

Dr. Blackmer has been picking up rocks since her childhood in Wilmington and Hockessin, Delaware. She received a B.A. in geology from the University of Pennsylvania, and M.S. and Ph.D. degrees in geology from The Pennsylvania State University. At various points in her career, she has worked for a geotechnical drilling contractor, a small environmental firm in Philadelphia, and a hydrogeological firm in State College. She has served on the faculty at West Chester University, Bloomsburg University, and Dickinson College.

She started at the Pennsylvania Geological Survey in 1999, with the primary task of geologic mapping in the Piedmont of southeastern Pennsylvania. She has mapped all or part of seven topographic quadrangles in Chester and Lancaster Counties, including Kennett Square. She has been Manager of the Geologic Mapping Division at the PA Survey since the end of 2010. This evening, Dr. Blackmer will take you on a journey through the fascinating geologic history of southeastern Pennsylvania, and discuss some of the practical implications of living here on the long-exposed roots of an ancient mountain belt.
