Pennsylvania's Caves Time Capsules of the Past

Join Rose-Anna Behr, the Karst and Sinkhole Specialist for the Department of Conservation and Natural Resource’s Pennsylvania Geological Survey,
to learn how Pennsylvania’s caves preserve a record of the past. Fossils, from giant wooly mammoths to tiny grains of pollen, reveal information about the past climate, ecosystems, and wildlife that roamed this state. Even stalactites and stalagmites keep their own record of the activities on the land surface preserved in microscopic detail. Discover what the caves reveal about the past.
