Pennsylvania has seen major changes over the course of billions of years. Looking at a geologic time scale often doesn't give us a true understanding of how much time it took for many of those changes. The Geologic History Stroll will allow us to spatially see how much time passed between major changes in geologic history by walking a certain distance for each eon, era, and epoch. Meet the park naturalist at the Kell Visitor Center at 1PM. The walk will take place on an as yet to be determined distance of Lakeside Trail.
