In the pilot episode of this HUDSY Original Series, we go on a mini road trip and visit three notable glacial erratics in the Hudson Valley with our geologist guide, Geo Beck (Becky Nesel) to learn about the region's glacial history. Whether they are made of one-billion-year-old rock or balancing precariously off a cliff, each boulder tells its own story of when the region was covered in a thick blanket of ice.
