Ice Ages of the Past
Course | Registration opens 2/1/2027 8:00 AM EDT
The Pleistocene Ice Age is the most famous one because it was the last one to affect our area. The mile high wall of ice never made it this far south but our climate and ecosystems were different than today. The Susquehanna River was the major player in carrying the meltwater away. We now know there were other Ice Ages during the geologic past that assisted in telling the story of plate tectonics and Pennsylvania.
